How to cull a chick.

None of us wants to, but sooner or later, if you hatch chickens, the time will come when you need to euthanise a sick chick.

Be prepared for it in advance.  Here's how.

Please note : Some people will find the information contained on this page painful.  If you're one of them, please either be prepared - or don't go any further.

When it's time to cull.

This is a judgement call we all have to make individually.  Each situation is different, and each individual will have a personal view.  The important thing is to find a way which will cause you, and the chick, the least possible distress.

The bottom line, though, is this question :

"Does this chick have, or is she ever going to have, a good quality of life?"

If the answer to that question is a definitive "No", then it's time to cull.

If you're still not sure, here are some more questions to ask yourself. 

  • Is she eating and drinking?
  • Is she spending most of her time asleep, even after the first two days post-hatch?
  • Is she thriving? - i.e. is she growing as well as the other chicks?  
  • Or does she look weak?
  • Does she have a condition you, or your veterinary practitioner, may be able to help with?
  • Are you satisfied that you have done everything possible to save her life?

Ask yourself, too, whether you are holding off taking action for your own sake.  It's hard to make this decision, but at the end of the day it's the kindest thing we can do for animals in our care if they are very unwell.

Do not, on any account, leave a chick in obvious incurable distress or pain because you can't bring yourself to euthanise her.  That is unfair and unkind.  It's heartbreaking, but the most humane thing we can do for a sick chick is to help her die in a dignified and peaceful manner.

Different ways to cull.

When I had to cull a very sick chick, I carefully researched different methods before choosing the one which felt kindest and which I had confidence in my own ability to do quickly, causing the least possible distress.  Before I discuss that method, here are some others I found which I could not, for my own reasons, use.

Breaking the neck :

This is also sometimes called 'thumbing' and involves flicking the neck backwards over your thumb.  When done properly, it is a quick and painless way to cull.

I didn't use this method because I had no confidence that I would be able to do it without causing extra pain, and possibly not killing cleanly.

If you're unable to face doing it yourself but you know someone who can, it's reasonable to ask them to help so that you learn from their knowledge.

Snipping the neck :  

Using a pair of sharp scissors to cut off the head.  Many people in rural areas use this method to cull very small - one or two day old - chickens.  It's quick and painless, but can be distressing for the person doing it.  It involves a small quantity (about a tablespoon) of blood.

Ether / starter fluid :

This involves putting the chick into an airtight container with starter fluid dropped onto an absorbent pad next to it.  A lot of people use it, but it's not recommended.  The starter fluid is known to burn, and is thought to cause pain before it takes effect. (1)

Veterinary visit :

This option will depend almost entirely on personal circumstances : cost, time, availability of vet, distance to travel for example.  If you're unsure you'll be able to face euthanising yourself, you can certainly be sure that this is a quick and pain-free possibility.

The 'baking soda' method.

What happens.

This is the method I chose when I had no choice but to cull.  It's quick, easy to do and doesn't require skills I don't have.

It will not be to everyone's liking, and there are no studies on very young chicks to assess exactly how much pain it may cause.

Anecdotal evidence, including my own experience, is that the chick is unconscious very quickly and dies within a minute.  

What you need.

One of the benefits of this method is that you probably have everything you need in your store cupboard.

  • One airtight container - I used a 'Tupperware' box
  • One smaller container - I use a smaller 'Tupperware' box
  • Baking soda (also known as bicarbonate of soda) - enough to cover the smaller container to about half an inch depth
  • White vinegar - about half a cup.

Arrange the smaller container inside the larger.  I added a cloth bed for the chick to lie on, and a pad of paper towel underneath the smaller box, in case of spillage.

  • Place the chick in the large box.
  • Add the vinegar to the small container
  • Close the lid immediately.

The reaction between the baking soda and vinegar causes a bubbling which releases carbon dioxide.  The bubbling calms down in a few seconds and you'll notice the liquid becoming brown.

If you have a transparent box, you're likely to see the chick slump to one side almost straight away.  After a few seconds you may see her flap a wing slightly. This is a reflex action and does not mean she is conscious.

Leave the lid on the box for several minutes to make sure the chick has gone, before opening the lid.  She will look as though she has just fallen asleep. 

I always bury my chickens in a special memorial area in  a peaceful wooded part of our garden which is covered in poppies in the spring and marigolds (which chickens love) in the summer.

Tributes will be published as soon as possible, but please bear in mind I don't have any administrative help with this - there's only me.  I will get to yours as soon as I can.

Thank you for your patience.

These pages are about common conditions which, with a little knowledge and some patience, can be resolved.
