My chickies are spoiled. The 25 of them have the entire floor (still complete with grass, dirt, and bugs!) of my 10' x 20' greenhouse to play in. They have plenty of water and chick starter in addition to their mini-free ranging. I see them eat worms, beetles, crumbles, grass....but they find shed and fight over feathers which they EAT. My bigger birds don't eat feathers, and never have. They were raised on the same chick starter but they were kept in a smaller brooder in the house without constant access to grass and bugs. So why are the little ones eating stupider things when there are so many other opions?
