I'd leave the lip and add a small ledge to the front. Depending on how high it is, maybe a 2x4.Here's a question! Just moved my broody box (a rubbermade tub) down to floor level. If I get a hatch they're due on Saturday or thereabouts. Here's the question: The box has about a 3" - 4" lip or edge at the door. When mom wants to bring the chicks out, is that too high for them to easily get back in?
