My 5 are still roosting on the high "leghorn' perch at night. It's well under the cover of the roof and has been very good in the hot weather, but I'm interested to see what happens when it gets really windy and wet. I can understand the two leghorns liking it, and even the little columbine who is part-leghorn I expect, but the other two are different sorts of Marans crosses and quite heavy by comparison. One of the leghorns is a very bossy top hen so I expect that, when she says "Come on girls, you can do it!' they all make the effort.
At least I don't have to bend down, remove the door and and get inside the coop to clean it up, it all falls in a neat line underneath.
Well, it would be neater if they all faced the same way overnight.
