My chickens used to roost on their little 2x4 roosting "bar" inside the coop until about a month ago when they started cuddling up in the windows. The windows are covered with fencing and are about 4 feet off the ground, so i am not terribly concerned for their safety but it just a little weird. Is it because of the heat? or are they just weird? PS i've replaced the chicken wire since this picture was taken, no one panic about the loose wiring!
