My little sizzle hen has a gross habit of pulling out her own feathers and eating them. She will also eat her own poop. She normally only does this when she is broody and recovering from being broody (no successful hatches yet). I have read in other threads here that this is a sign of protein deficiency, but she is my pet house chicken and is spoiled rotten. She gets scrambled eggs every morning for breakfast, and i place a dish of scrambled eggs with shells and a big handful of chopped greens in the brooder for her while she is sitting on the nest. She also gets fermented grains. I can't imagine that it could be a deficiency since she gets plenty of protein and doesn't always finish her food. What could the problem be?
