We've had bad experiences raising chicks, losing many to predators, disease and sudden death, over the course of the five years we've had chickens as pets. None of our chicks live past a few years (although we've fixed the predator problem). So I'm nervous now about raising chicks. We have eight that I've just put in a small coop within the larger coop and run. They are about five or six weeks old. One has started to sneeze, so I'm wondering if this is normal. She has no runny nose or closed eyes and is eating plenty of fermented and dry feed and is active. Thanks for your time!
