I have a coop that's about 7' square and 8' high. That's only enough space for about 5 birds by my calculations. I'd like 10 layers, if possible. Could I add a loft to increase the usable space? Or am I better off with more roosting real estate? If I go to the trouble of making a loft, will the ladies actually use it? If they don't, is there a way to entice them? Do they need ramp? Or are they happy to jump/fly between levels? Also, my roo is giant and his wings are tiny. I honestly don't know how he gets up on the roost. It's, like, 2' off the floor. Do I need a ladder? Should it be a board with slats? Once I saw one that was lashed-together sticks.
