That is a great idea! I was wondering about those when I was looking through the pics as well. Love seeing the pic your Suede.Xander's coop where he is now was formerly full of Blue and Buff Orpingtons. They were so huge and the area so small that I could not find a good roost situation for them. So, I built big Suede a roost shelf to sit on. In winter, I put hay or shavings up there. It's only about 27" above the ground, easy on the legs, no balancing required, doesn't get in the way of floor space, etc. So, Xander inherited the shelf. Now, there's only one blue Orp left, big old Dusty, who probably weighs 9-10 lbs herself and of course, Rowena and Wendy, Atlas's sisters, don't really need it, but we just decided to move the entire shelf over there. That is plastic garden fencing, now re-stretched on the frame after all these years of use it's had.
Here is a photo of Suede shortly before he passed away snoozing on his shelf. See how it cradles his big old body?
Your comment about the hens allowing themselves to be overmated is certainly true in the case of our hen who is prone to mating injuries. After keeping a keen eye on her for the past month I don't think our rooster is being rough on her as she is just a little hussy, bless her heart.
