We are getting ready to start my coop. I had the "great" idea that it would be really nice to have a small greenhouse attached to it. But am not sure of the problems that might occur with this set up. We will be pouring cement for the coop and the need for only three walls of glass will cut costs. So, let me hear your thoughts, experiences, ideas-- pros and cons! The coop will have T-1-11 plywood. Thank you.
