We have three golden comets (9 months old) that started eating their poop yesterday. Last night in the coop, they ate ALL the poop in the hen house. Usually they run when I bring the kitchen scraps out in the morning and love to eat them. Today, they completely avoided the scraps and all go crazy when one poops and eat it up as fast as they can. YUCK!! Last week, the girls were free ranging in our backyard when 2 foxes came and took away 4. I found the remaining three on the far end of our property about an hour or 2 later. Are they stressed from the foxes- it was a week ago and they have been fine since then. Do they have a vitamin deficiency? They are still laying eggs well and drinking water and eating their feed. Please help me!
