My new Dark Cornish from @Minniechickmama have been sleeping in a nest box all huddled up at night and pooping all over in it! If they don't start using the new low roost I built for them I will have to start blocking the best boxes at night. Little turds!
Sorry about that! They roosted here. I don't know why they would start doing that to you now. Maybe they are skeerd of the new flock they are in? But if you have to block the nests, after a few nights they should catch on, I would think.
