I'm new to chickens, though I've had various other birds (raptors, waterfowl, parrot family, etc) off and on over the years. I know about dust baths and such and have seen other birds do it, but still freaked out when I first found one of my 2 wk old chicks writhing in the brooder box in her shavings (ok, I thought she was having a seizure LOL). I next freaked out when I moved them out to the coop and found one of them laying out belly to the floor near the door with her legs stretched behind her in classic "rubber chicken" pose and she didn't even move when I opened the coop door and spoke to her. She finally looked up as if to say "What?" and I realized she was napping. Now I notice that they all do that fairly frequently. they also lounge on their roosts even though it's the middle of the afternoon. It seems I learn something new every day- guess I shouldn't worry since one of my dogs and I have a penchant for napping on the couch in a sunspot in the middle of the afternoon whenever we can steal the time!
