We are moving. I currently have an A-frame tractor type coop: coop area is 4x4 and run is 6x4. New house has much smaller yard BUT it has a "shed" on one of the narrow sideyards. I'd like to section off part of the shed and then attach a run to it. This is the wall of the shed that faces the backyard: my husband is 6'3" for reference. There is no opening on this side. My idea is to put an access door for me and a small door for the girls on this side, add a wall on the inside (maybe ~4 feet in) so the rest of the shed is still useable and accessible from the front, where the gate is. Anything I should beware of since it is right up against the fence and the house siding?
