I am going to begin construction of my coop (no birds yet) soon. I will be building it inside an already existing 12'x24' lean to on the rear of a detached garage. The coop will be at least a 4'x4' size. The run will be behind the lean to. My reason for building it within the lean to is: 1) additional protection from predators and weather 2) good dry lean to storage for feed, etc. 3) easy07 to add electric from garage, etc. My dumb question: how high can the coop entry be off the ground. Will my chicks climb a steep ramp? I ask because some framing already exists in the coop location which would help keep cost down, but it would put the coop floor about 4' off the ground. Thanks for the help............ Jeff PS - I am in a small town in MI that has told me chickens are banned (as considered livestock). Considering MI Right to Farm Act, I'm going forward anyway.
