That's one of those things that depends on your climate and the environment. If they're outside and there are wild birds flying overhead, I would put a full roof on to make sure your quail aren't exposed to the poop of the wild birds. There are a lot of diseases that can be transmitted that way. My birds are inside a greenhouse, so they don't have exposure to the poop, so I cover part of their roof so they have shade, but that's all.Thank you! Very good article.
I guess the one think that I didn't see there was if its recommended to have it completely covered with a solid material like wood or some type of lightweight roofing material or only partial cover it and left the rest covered with the 1/2 HW cloth.. Not sure how smart quail are as to getting out of the rain and weather!
