I'm talking with someone about building a coop/run similar to this one: https://www.backyardchickens.com/web/viewblog.php?id=33943-rancho-chickacabra For some odd reason, when he drew up his design, he put the cleanout door on the inside of the run. I can't figure out why he did this when I gave him the above link. Is there any reason why it would be better to have the big door on the inside?? Is he thinking it would be easier to build that way? The only advantage might be that the chickens wouldn't get out while you're cleaning. But it seems like it would be messier and harder to get stuff out, since it would have to be carried out of the run. WWYD?
