My 4 hens are now just 6 weeks old and tonight is their 3rd full night in their coop outside. Tonight and last night as I went out to close them in and do one final check, they were in some sort of hysterical mode. I don't know if that's what it is, but they sound as if someone is in some sort of crisis. I check them and everyone is fine but I don't know what in the world the commotion is over. They eventually settled down but it was pure chaos for a half hour or so. Any thoughts?? Thanks,
