I also had a cockerel that did a number on his leg, ok, a few cockerels.. rotten hormones. Anyway, it took a few weeks for them to heal, but heal they did. Only they'd lay down a lot and take the pressure off, and when they'd stand, the leg was always up, and they'd kinda hop along with their wings out a bit for balance...
When the project is all done, I will have a divider "wall" (chicken wire) between the back 2/3 and the front third, with the feeder and watering being able to be done from my side of the wall, just in case i ever need a bird sitter. I want to build nesting cabinets along one wall too, like the ones HH (?) had last year. That would give the broodies a little more space than the rabbit cage, and then they would have a little more time before they had to abandon the nest with their babies. I also want a little nook for me, so even if the weather is bad i have a place to sit with them and not have to fear sitting in chicken poop!
