Mine don't. They make nests in the shavings and sleep there. I have a small coop for my three, and the roost is in there but they use it as a step into the hutch and sleep on the shavings behind the roost pole. My Dad is giving all his children some inheritance $$, (thanks Dad!) And I'm going to have alot of fun building a decent coop and run. With the new coop I will have roosts in there. Curious to see if they sleep there or not. But I do have roosts in the run, and they're on there all the time. Do I have weird chickens?
