Hello, I have 2 peacocks I bought in the Spring, this fall I started letting them out during the day, and they would go back in their pen to roost at night, but then started roosting on top of the pen.. I was fine with this, but now that it's bad weather, Freezing Ice, I'm worried about them, when it's rained they get on my porch during the day, but go high to roost at night, what can I do to get them more shelter? I don't want to loose them to the Winter Weather, but they kind of have a mind of their own.... Any suggestions?
