I just acquired a 10 month old EE roo that may be pooping bright Kelly green poops. They're solid normal consistency, white white caps. I've narrowed down to him or 2 other hens he's in with. He has runny normal colored poop sometimes. The family I got him from could no longer keep him bc he was crowing and they live in the city. They are Chinese and only fed him Chinese people food, then let him free range in the backyard. Now he is eating chick grower crumbles bc he's in with some young-uns, and also gets greens grass/weeds every now and then when I let him out. He eats, he is not starving. Could the bright green pooos be from change of food? What do I do about it?
