I put carefresh in the bottom of their brooder and paper towel on top of that because they peck at it and eat it. Now they rip bits of the paper towel and eat that! They really go at it, filling their little crops with paper towel!! What to do? They eat their crumbles too but geez they seem to fill up on paper towel. What do I do with these silly chickens? They are three weeks old.
