You've decided to raise guinea fowl and like most people, you've decided to get started with guinea keets rather then adult guineas. (smart move!) Guinea keets are about the cutest little things you will ever see. They have bright orange beaks and legs and scurry around like crazy little bugs! Luckily raising guinea keets is almost the same as raising chicks so if you've raised chicks before, keets will be just as easy.
The brooder set up that you'll need for guineas is the same as it is for chicks. You can see my recommendations here in Brooder Basics. I like to raise guinea keets in their own brooder separate from regular chicks. Since keets are so small, they can easily be trampled or squashed by bigger chicks. The only illnesses I have seen in guinea keets is spraddle leg and pasty butt so they are pretty hardy for as small as they are.
