My Buff Orpingtons and Brahmas just started laying but they keep laying on the ground. I built nest boxes in the coop about 2 ft. above the ground on a shelf thing. They do go up their and investigate them but they haven't laid in them yet. Even when I had the nest boxes on the ground they wouldn't lay in them. I'm using milk crates and cardboard boxes for nest boxes right now. We'll probably build nice wooden nest boxes eventually. Today I almost stepped on one of the eggs. But how can I get them to lay in the nest boxes???
