Yes. They can even sleep on their sides to really freak you out. However, they should pop awake & be alert when awake.So I got the coop half built and decided it would be okay to buy our chicks. We're now the proud owners of 2 Americaunas, 2 RIR, and 2 Black sex link chicks...at least for the moment. Got them home and within an hour one of the BSLs seemed to be spending a lot more time on her belly than the others. Then she started laying its head down on the bedding. THe BSLs seem to be a little bit older than the others, so maybe its a behavioral difference based on age. Temp on one end of the brooder is 95 and the other is 83. Now the other BSL seems to be acting similarly. I've seen them all eat since we got them home. Wife is thinking that just may be the way they sleep. Do chicks normally sprawl out when they sleep or do you think something is wrong with this chick? Whatever help you can provide will be greatly appreciated!
