This is a post which follows the 1st one in coop design. I have no covering, due to total inexperience, on the roof of the inside of my coop. Didn't think they would try to get up where they did tonight. This was a panic moment for me. The 4 (of 7) of them, with the rest waiting their turn, got up on the plate, where the roof part meets the base. The roof nails where sticking through, and I couldn't reach them with out a ladder. I ran to the house, got nails, cardboad, and a ladder. When I got back in to make a quick fix until tomorrow, the one chick, decides to go for a very small area, and can't hold on, and just plummets throught the 2 levels of roosts they sit on, to the ground. I watched her after that happened for a bit, she seemed so shaken up, but no visible injury. What should I be looking for? They all ended up where they have been sleeping. A couple of questions? Do I need ladders to go to different levels? Can they fly up there? Get down with no injury? I gues I need help and advice. I can provide ladders for them, just didn't realize they needed them. HELP! Please be as direct here as possible as I freaked out.
