Its adorable! One thing about the wire under the roost. Is it hardware cloth? If so, the poop wont fall through it, just so you know. Something with 1" holes works better for that. Personal experience.
Thanks everyone for all your wonderful comments! We're located in Los Altos up in the SF bay area. Yah, we realized the holes in hardware cloth was too small once we saw the size of the poops coming out of them as they got older
We'll probably cut the wire to make bigger holes but for now i'm just dealing with the poop pile on the tray.
It's 2 1/2 feet from the ground which made for a pretty high ramp at first but we raised the bottom of the ramp to make the slope easier for them to walk on.
