How weird is this? My coop has an "upstairs" and "downstairs." Upstairs is accessed via a ladder/plank and the chickens can go up there any time they want. That's where the nesting boxes and roost are. Downstairs is open to the ground, but enclosed with chicken wire. In the evening, we let the girls run around our fenced in yard. They always put themselves to bed when it gets dark, and I close up the coop. Every night, they pile up in a corner inside the downstairs part of the coop and go to sleep. I swear, it's just like a pile of puppies. Right now, I'm assuming they stay downstairs because of the heat. It's definitely cooler than upstairs. Anybody else having a similar experience?
