I have a large coop 10 x 12 and a small coop 4 x 8 with lots of roost space. This year is my first year with silkies, showgirls and sizzles. I have four birds that puppy pile on the floor to sleep and will not roost. As a result they frequently pick a spot they end up pooped on. I really want to build them a place of their own. I am in the far north of Michigan with cold winters. I am looking for ideas about what to build for these little guys. Can anyone give me some ideas what to do different for them?
