I have 5 surviving silkies going on 7 month's old they basicly right now have a Posh 2 room coop with ton's of nest boxes.They were some of my first out this spring and they got my old frizzle cochin house which has board floor on one half with Way too many nest boxes and the other half is concrete.But Everynight for the last 3 month's they just all huddle in a corner together.It's hot here right now and I had hay on that whole side when I first put them in there I know silk's dont really roost and cleanup this week so just going to put a heap of pine shaving's for them.My other coop I gotta watch when I go in there lol OEGB roost in rafter's I run for the water's and feeder's until they all decide to go out or i get a present on head. lol.I have some that like to roost high and other's like floor or and low box huddled.
