I had previously read that a window at roost height was recommended. Now I read not to so my question is...should i make a window/vent at the roost level or above the chickens height when they are roosting? If above it..how much above it? We are in texas with hot summer months. I had planned my windows on the side of the coop with the most breeze and was going to start the window about 3 inches above the roost bar so they could get a breeze while roosting. The windows will be covered in hardware cloth. Despite our best efforts at making sure there werent any drafts but enough ventilation our roo did get a little frost bite during our very cold spell. Any suggestions would be appreciated!
