I need some help. I am making the rabbit hutch into a small coop. I think everyone has a general idea of what a rabbit hutch looks like. The questions are; Where should I put the ventilation so it isn't hitting the birds. I do have an idea, but would like other's thoughts. The bigger issue is how to open a door to allow them into a run. I am thinking of a door that I can slide sideways from the outside of the run, but I know others have coops that look like rabbit hutches (or runs that are only a few feet high). What are other ways to make this work?
