I must have the only chickens who don't like oatmeal! I found scratch and meal worms to be their favorite. I throw it in their run with a few bunches of leaves. They have fun searching for the treats. I also give them a bowl of chopped greens. They love this almost s much as the scratch! Once the weather warms a little it will just be the worms for protein and greens. I don't want them to gain weight from too much scratch.
