My year-old Cookoo Maran had plucked a few feathers, but we went away for two days--they had plenty of water and layer feed--and she appears to have plucked most of her backside and legs clean! I had friends check for eggs yesterday afternoon and the hen had not plucked, so this is within an 18-hour period. Other than the plucking and what appears to be some loose mustard-colored stool, she seems lively, layed yesterday and is eating well. Their run area is 4x5 for three hens. Has anyone expereince this? What should I do? Is this mites (I have DE in their roost and nestbox)? Boredom? Help!!
