My Roo's comb is losing its red color. He is 8 weeks old and seems to be fine otherwise. One of his brothers mysteriously died last week and noone else shows any signs of sickness. I have 12 other chickens in the coop with him right now. They get some free range each day. They have dirt and pine chips in the coop. Fresh water daily. Am I being an owner hypocondriact? Is this normal? Thanks in advance!
