Every evening, around dusk you will find me in our chicken run lifting out 3 or 4 hens from one house and putting them into the other smaller one. If they had their way, they'd all huddle up but I'm not happy as I'm paranoid about the bugs. Maybe instinct tells them that the bugs won't survive this frosty weather, I don't know. But each night, I get muttered and clucked at. Having said that, last night I found a bovans goldline already in the smaller coop all alone, so maybe its sinking in!
