So I just found out that we will be moving in a couple of months. That means a new coop for my flock. I'm already day dreamin about my ideal coop. I might get to start from scatch this time, so I'd like some input. I've been pouring over coop pictures and posts. I've noticed that some folks have square roosts, some round and some tree limbs. What are everyones thoughts on these types of roosts?
