We are making our coop out of a 16 x 10 metal storage building. We are adding two windows to catch cross breeze. It has double doors and we're fencing a pretty large area for their run. There is nothing but floor space in there now. I need some ideas on what I should build for the inside. I have one week until back surgery so I will be having to move my chicks out there next week. They will be just over three weeks old. I want to build the inside to accommodate them now, high enough that I can interact with them when I can't bend, but that will serve a purpose when they are grown. Any ideas? Their brooder is a baby crib but with 20 of them, they have about outgrown it already.
