Hello. We just started the awesome experience of keeping chickens about a month ago. We started out with two hens and then decided to get 2 more this past weekend. When we designed the coop we designed it to be big enough for 4 hens to sleep in (they have a large free range section of the yard and spend most of their time their). We have two roosts that we thought were big enough for 2 hens each. However, when we added the 2 new hens last weekend, in typical chicken fashion, they made the roost big enough for 3 hens. There is no way they can possibly cram another hen on one roost so one of our girls roosts on the other roost alone at night. I'm not too concerned about this now since the weather is so warm, but will it be a problem when winter comes? We live in northwestern Virginia on a mountain. Winters tend to get chilly. Would it be better to somehow rig up a longer roost so all four can get on one? Should we get another hen (a bit concerned about coop size, but again they only sleep inside, the rest of their time is out in the yard)? Or will this not be a problem when it gets colder?
