Hi everyone, I'm brand spanking new to this chicken-rearing thing. My wife and I picked up a batch of new (1-day old) chicks 3 days ago. They all look good, except one droopy looking one. It's head is usually droopy, it seems to fall asleep on his feet a lot, rarely opens its eyes, typically is off on its own and is slow to react when I come in to change the water and food. Should I cull him? I'm using Storey's Guide to Raising Chickens (Gail Damerow) and this seems to be the description of a chick that 'isn't feeling well'. I don't want the rest of the chicks to get sick, but I don't want to cull too early. Any suggestions? Thanks!
