What should chickens eat to keep them healthy and happy?
You may know that chickens should eat different types of food to meet their nutritional requirements at different times of their life - but do you know what they are?
It's critical to their development that they get the right balance of protein, fats, carbohydrate and vitamins. If you're anything like me, you will be completely confused as a new chicken keeper.
When I started keeping chickens I couldn't work out what that balance was, and the information was scattered all over the internet.
I wrote this article so that you won't be. It's based on my own experience together with information I've learned from reliable sources.
Which is best - commercially produced or 'make-it-yourself' food?
Many people worry about the contents of commercial food and so would like to make their own.
Personally I don't do this for one simple reason : the balance of nutrients is a very delicate one which commercially produced feed has come to by scientific methods.
It's very difficult to get the balance right when making your own. And an imbalanced diet can create health problems in the flock which I'm not prepared to risk.
It's not hard these days to find a source of food which is organic, free of antibiotics and free of genetically modified ingredients.
I recommend some good quality products during the course of this article but you don't need to follow my recommendations, and buying locally is likely to be less expensive anyway.
Just ask at your feed store for a product which is chemical and GMO free.
This is what I cover in this article. Click any of these links to go directly to that information.
Free ranging your flock is great if you can do it - but what else should chickens eat?
Chicks : hatch to about 7 - 8 weeks.
Chicks at the point of hatch do not need to eat immediately. The
egg yolk which they absorb in the last day before hatching will keep them
nourished for the first 24 to 48 hours.
After that, they should be given a chick starter feed, also known as chick crumbs. It's specially formulated with the high levels (about 20%) of good quality protein, and the vitamins the chicks need during this stage of intense development.
For the first couple of days, sprinkle it on some kitchen paper in
their brooder box : the noise of the crumbs dropping will stimulate them
to peck. After that they can graduate to a feeder.
Dropping chick crumbs onto kitchen paper will stimulate chicks to investigate by pecking.
Leave the food available to them all the time. They're not like puppies - they will regulate how much they eat.
To make sure they are getting a balanced diet chicks need to fill up on this before you give them any treats. For advice about providing treats to young chicks click on this link which will open in a new window so you can have a look after you've finished reading this article.
Chicks should eat starter crumbs until they are about two months old.
Why 'about' two months?
Different feeds will have different recommendations according to the
levels of protein they contain. You should take note of what is recommended on the product. If there's no recommendation, use the
two month (8 week) point as the time to change - but don't panic about it. A week or so either way is not going to make much difference.
I have chick crumbs left over at the eight week point I generally use it
up by mixing it with increasing quantities of grower feed - the next stage - so that they graduate from one to the other over a period of a couple of weeks.
Don't leave any grain lying around
thinking you'll use it with the next batch of chicks - it has a
nasty habit of absorbing moisture and going mouldy which will cause
major issues for the wellbeing of your next hatch.

Grower feed : Pullets and cockerels from 8 weeks to about 18 weeks.
Both male and female chickens should be moved from chick to 'grower' feed at around 8 weeks and should remain on this until shortly before 'point of lay' - the age at which females begin to lay eggs.
Grower food contains less protein than the starter -
around 16% - 17% as
opposed to 20%. The chicken just doesn't need to eat as much as growth slows down somewhat.
important not to overdo either protein, as found in starter crumbs, or
calcium which is found in 'layer' feed. Both can do irreparable damage
to the kidneys.
A commercially produced grower product
will ensure that your flock eats exactly the right balance of nutrients at
the point of need.
Try encouraging your growing birds to eat from your hand - it will make them easy to handle later on.
Why 'about' 18 weeks?
'Point of lay' is usually around 20 - 21 weeks, but chickens are not robots! Some are much later - around 30 - 35 weeks is not uncommon for larger breeds - and some individuals just take a long time to get into the swing of things. I have had a hen not begin laying until she was a year old and I had almost given up on her ever giving me a single egg.
Again, don't leave food lying around if your chickens reach 18 weeks and you have some grower feed left over. It's fine to mix it with their "big girl" food so they graduate from one to the other over a couple of weeks. Leaving it for your next batch of pullets runs the risk of it absorbing moisture and developing a mould which can be fatal.

Layer feed : Point of lay onwards.
From the point they start to lay eggs, your chickens should eat a good quality 'layer' feed which is balanced to make sure hens are getting the correct levels of calcium to promote healthy bone growth.
Adult hens need less protein but more calcium and phosphorous
than youngsters, so a typical layer product will contain around 15% protein
but an increased calcium ratio of about 2%.
the increased calcium levels, making an egg
requires a larger amount than feed alone can give. For this
reason, laying hens will require additional calcium to be fed in a
separate container. For more information about this see this link which will open in a new window so you can come back and finish reading this page.
Laying hens need to eat less protein but more calcium.
Layer food comes in either pellets or 'crumbles' (sometimes also called 'mash') and it really doesn't matter which you get - the content is the same. Pellets tend to be a little less messy as they're not as easy to kick out of the feeder.
Chickens should have layer pellets or crumbles available to them all day. You don't need to worry about them over-feeding themselves; they're very good at regulating the amount they eat.
Make sure you either use a rodent-proof feeder, or take the food up at night. Your flock won't eat after dark anyway, and leaving grain around is a sure way to attract rats to your coop - as I found out to my cost.

What should roosters (cockerels) eat?
You may see some advice on the internet that males should be fed a different type of food to females - one that's lower in calcium. The practicalities of this would in any event be virtually impossible to manage unless all your males are kept separate - always - from your hens.
Will layer feed harm them?
No. It does contain some additional calcium but not enough to do any damage to your roos - which is why oyster shell should be offered in a separate container, never mixed in. Hens need it to make strong-shelled eggs, and the roos will not eat it because instinctively they know they just don't need it.
For more about oyster shell see this page (which will open in a new window so you can return here to read the rest of this information).
Should chickens eat medicated or unmedicated food?
Poultry food can be found in both medicated and unmedicated form and it's a question I'm often asked - should chickens eat a medicated feed?
A medicated product protects against (but does not cure) the disease coccidiosis, an
infection of the digestive system which is most common in young chicks
and can be fatal. It tends to breed in warm, moist conditions.
I have never used medicated products with any of the chicks I've hatched myself,
nor with any of my adults. I keep my chickens and their environment
clean and dry, so don't see the need. I have never had a problem with
chicks picking up any form of illness or virus and I prefer them
to build up their own immunity.
Why do people recommend it?
Chickens hatched in
large-scale commercial farms are given medicated feed because they're
raised in close proximity to other birds, often with insufficient
space and, sadly, in less than ideal conditions. They are therefore
more likely to develop illnesses which then spread very quickly across
the entire flock.
Even chickens described as 'barn-raised' are kept in crowded conditions which require medicated feed.
People who raise chickens on a small scale may decide to give a medicated feed as a kind of 'just in case' insurance against coccidiosis, so of course it's a decision you must come to personally. But if your flock is well cared for, it's my opinion that there really should be no need.
A word about Genetically Modified Organism (GMO) feed.
GMO feed has been given to chickens in the commercial farm industry since the mid-1990s and many food products available to backyard chicken owners contain genetically modified corn. Government departments will state categorically that :
"There is no food safety — or any other risk — to the health and well-being
of consumers when they consume chicken or other animal agriculture
products (e.g. eggs, dairy), which have been raised with genetically
modified feed ingredients". (National Chicken Council, 2012).
Despite this many individuals do not wish to give genetically modified feeds to their chickens and it is entirely possible to buy products which have no genetically modified ingredients.
Any product that has the label 'Certified Organic' is not permitted to use GMO ingredients. It will generally also be prominently labelled 'Non GMO'.
The only drawback of non-GMO feeds is that they tend to be more expensive - but many, including me, feel the additional cost is worth it for the peace of mind of feeding a natural, organic product.
In case you missed it, learn more about grit and oyster shell.
Chicks should eat grit as soon as they begin to eat anything apart from commercial feed.
Laying hens need to eat oyster shell from the point immediately before they begin to produce eggs.

A lot of "facts" you'll find on the internet are generally speaking people's individual views, often based on inaccurate information repeated from poor quality sources.
The information I provide in this article and others is based not just on my own experience, but on evidenced facts from scientific, peer-reviewed research and evidence from highly respected and experienced poultry keepers such as Gail Dammerow.
