I put the plastic on the coop tonight. It was horrible to watch but funny at the same time. I wish I could afford a camcorder cause this would have been one of those moments. When I let my toddlers out to free range I put the plastic on the coop because we are under a Frost advisory tonight. I knew this was not going to go over well cause at the top of the coop it is open so they can fly over to the pen. Well they roost on the wall every night. I reckon you need to see the pic to understand. So when they went in for the night, they kept flying up to the wall. Then they would hit the plastic and fall down. They did this repeatly. Finally they all came out of the pen/ coop to me and I swear they were thinking/ clucking, Somethings wrong here I went into the pen and they followed me, I told them they have to find a new place to sleep. Dont tell me chickens dont understand what we say, cause they all went in the chicken door to the coop and got on the empty roosting bars. I guess they adapt better than what I thought. I was prepared to chase them out of the plum trees tonight.
