What I was thinking was a coop on each end of the run. The reason would simply be that I think my wife would like that more than she'd like one large coop, and that two coops might offer more flexibility. One potential downside might be that the number of hens per house might be too low in cold...
I'm curious if anyone has had two coops using one run. I'm wondering if the girls would pick one or the other to stay in, and if it would end up being a bunch of hens that didn't get along well.
