we are making a new coop and can not free range, we have one coop out of an rv, which we will still use, I would like to know if anyone has a coop with run inside the chicken yard, our coop is 27' long and the yard is 30 by 30, I would like to put a covered run so they have a place to go in the winter like last winter they got locked in coop when it snowed, I would like a run little longer then coop and about 14' wide with wood up 3/4 then screen, put it on the side that will not be hit by wind. any ideas.
