I have a kinda dumb question. Do my chickens need anything besides lay mash? Do they need/benefit from scratch grains to? I have a little roo in with my hens to. Is he fine on lay mash to since he's in living with them, so I cant really seperate the foods. I also havent been giving any grit of any kind because they have a decent sized run with tons of tiny rocks and whatever else they feel like eating it in. Those who are laying have strong eggs with hard shells so I figure they are probably getting what they need. Am I missing anything as far as diet or does it sound like they have everything that they need just fine?
