I have some wood frame windows that I would like to install in my chicken coop. I have notice that some people have put the hinges on the bottom thus allowing them to open from the top. Wouldn't this just channel rain into the coop during the spring and summer? Is there a hidden purpose that I'm not getting? I was thinking I would hinge mine at the top thus allowing summer ventilation while keep out the elements. Any suggestions? Maybe left or right hinges instead? haha Thanks for the help.
