But are they still too young to go outside? When is it warm enough? How do you keep them safe? And how should they be introduced?
It happens to us all. Those cute, fluffy babies start to grow.
They outgrow their first brooder, so you give them a bigger one.
They try their wings, so you put some mesh over the top of the big brooder.
They start to smell, so you move them from the house to a basement or garage.
But sooner or later, they need to go outside - for everyone's sanity.
If you have adult chickens who have been together in a flock, you will need to introduce the chicks very carefully to the big girls (and boys). Chickens can be ruthless with newbies, and little chicks will stand no chance against adult hens and roosters intent on establishing the pecking order.
But before you even start to think about integrating your chicks with the flock, it's a good idea to get the babies used to being outside at all.
After all, it's a big, scary world for a chick after the safety of the brooder.
That's what this article is about.
These littlies were five weeks old when they first went outside. The temperature had been too low to allow them out before then.
As you can see - they loved it! You'll also see the netting in this video, which I refer to below.
You'll also see that this was before I learned the lesson about my chicks being able to use their "place of safety" box as a launch pad to escape from the safety of the netting.
Lesson learned - the hard way!
This will depend on the time of year you hatch and what the weather is like in your area.
If babies are raised by a mother hen, of course, they're outside from day 1 - but they always have their mother to run back to for instant warmth when things get a little chilly.
If you've hatched eggs in an incubator, you'll need to take some precautions to make sure the young ones don't get chilled. Cold and damp air can kill a chick very quickly.
Wait until they're at least four weeks old before you introduce them to the outside world - and only then if the weather where you are is warm.
If there's snow on the ground, don't do it.
By four weeks they will have some feathers, which are their main way of keeping warm. But don't be deceived by wing feathers: they develop first but the rest of the body is still likely to be mostly covered in down.
And down does not retain heat.
This means they won't be capable of keeping themselves warm for long at this stage. They will usually be fully feathered by about week 11 - 12, depending on the breed.
You can't just take babies outside and leave them to fend for themselves. They are extremely vulnerable. So think through your own situation.
When my babies first venture out I generally leave them outside for no more than a couple of hours. That's enough time for them to explore, start to get used to strange noises (which will help them a lot when they finally go into the Big Girls' run), and not get chilled.
But as ever, use your common sense and your knowledge of your own flock.
Do they look as though they're puffing up their feathers? They may be getting cold. Are they peeping in that frightened way you will have heard before? If so, what's scaring them? Can you help or do they just need to go inside?
Most importantly, don't leave them by themselves. You need to watch them. Take advantage of it - what could be nicer than spending a couple of hours in your garden on a lovely warm spring day watching the antics of your babies?

1. Buy something to contain them. You can rig something up yourself fairly easily using wooden poles and chicken wire.
I don't use an electric netting because I personally believe it's too harsh.
At the bottom of the netting the holes are only 5cm x 5cm, so small enough to contain chicks after about 5 - 6 weeks old, depending on the breed of course.
If you're putting chicks in it before that be aware that they can escape!
It's nice and high so I also use it at times when introducing newbies to the adult flock, when I need to keep some hens separated from others - or when I need to protect my plantpots from hens intent on dust-bathing in them!
However, be very aware: netting like this will keep chickens in but it will not keep predators out. It's not designed as a safety device, it's designed as a way of containing.
2. Use your small brooder box (if you used one) as a place of safety for your chicks - they're used to it, which is important while they get used to so many different sights and sounds outside.
If you didn't use a brooder box, any cardboard box will do.
3. Think like a chick! They are curious creatures. They love exploring and they always seem to think the grass is greener in someone else's part of the garden.
Be careful, for example, where you put your 'place of safety' box. The first time I did this, one of mine decided to use it as a springboard to help her escape.
She was mauled by a dog (because I also broke the golden rule and left them outside while I went to do some household jobs) and I nearly lost her.
So learn from my mistake. Place the brooder in the centre of the area you're using, not close to the fencing!
4. Beware of dogs and cats, not just foxes and coyotes! Remember that domestic animals are not necessarily a friend of chickens, especially little ones. At the very least, they will be tempted to 'play' with those squeaky balls of feathers.
At worst they may see them as lunch.
It's not just your own animals you need to be aware of. Neighbouring dogs will be attracted by the smell; neighbouring cats will be attracted by the noise.
Both will kill.
5. Use the time to 'bond' with your chicks. You can't climb into the brooder with them! So use the opportunity while they're outside to sit in the run with them. Take a book. Enjoy the outside.
And most importantly, get to know them. It will pay dividends when they're older and much, much bigger.
