I live in Ontario Canada. I have an odd problem with one of my EE's. She 8 months old (and STILL has not laid her first egg btw!) and she never sleeps squatting down on the roost at night. I know this because I have a webcam in their coop and since she first moved in there 2 months ago I have never once seen her not standing...even at 3 in the morning All night long she stands there lift one leg up and down...but will not squat down. She drives the other chickens crazy because she periodically tilts over and either falls off the roost or knocks them off. She doesn't appear unusual in any other way and I have seen her laying down in the sand box dust bathing so I know she can squat down. My concern is what is going to happen to her feet this winter? We hit temps of -30C (-20 F) frequently. I know it was important to have the roosts wide enough that their feathers cover their feet....but what happens to a chicken that sleeps standing up? Anyone have any suggestions?
