My hens are disappearing from our coop. We bought 6 chickens around easter of this year. We wound up with 3 hens and 3 roosters. One hen and one rooster had disappeared a couple of weeks ago. The rooster became very mean so we have been shutting them out of the coop, and leaving them in the run. Last night we shut our last 2 hens in the coop, and this morning they were gone? the roosters that we leave outside of the coop, however, are still there. I don't understand what is happening to them! I would think a predator would get the roosters since they are outside of the coop. Please help!
