Hi all, I have my 5 chicks in a pretty large box. I put a 250 watt bulb on it...pretty high up because they were all bunched in the furthest corner when it was lower. They are now laying all over the box. My question is, is it normal for them to lay with their necks stretched out? They are laying down flat on their tummies with their heads stretched as far as they go and laid on the ground.
