Glad I found this thread, I have noticed our 8 day old chicks holding their wings out when sitting and they don't move away from the light either. I don't see them holding their beaks open panting, but it does look like they are breathing kind of heavy. Them temp was a little warm today...it was around 90. We moved the light up a little but we also just added 4 more day old chicks to the group so we are trying to keep everyone happy. I'm just hoping they are smart enough to move away from the light if they are to hot and not bake themselves to death!
