I got four chicks 3 days ago, and when I brought them home they wouldn't stop peeping! We've spent lots of time cuddling with them, and the first couple days they seemed pretty normal. But last night and today, every time I check on them they are just laying in the bottom of the brooder, not making any noise. They are not too hot or cold, they have plenty of food and water (which they were partaking of at least yesterday). Are they sick, or do chicks just sleep a LOT once they get settled in?
