in a small coop. Plan on 3 of the larger hens, big tummy and fat butt. The ones that will not be as likely to be getting over fences. So all this talk of roosts and such had me out taking my first measurements today (added to my BYC page ). Now I need to know how tall your larger hens are when roosting and how far down their tail might go. Don't want head bumps or dirty tails because of how I set up their bedroom. I'm sort of thinking I need two short roosts, meeting at right angles to give them adequate head room ?
