My chickens are currently staying in a temporary coop in our garage until Spring when we can build them a new coop. The coop they are in is 5x7 and about 7-8ft high. The top is not covered, because we couldn't come up with a good way to cover it. I purposely only put the highest roost 3 ft off the ground thinking that that would keep them from jumping out. I was wrong. One of my girls found out that if she stands on the roost, she can jump all the way across the length of the coop and up onto the top, and then she jumps down into the garage. Well, monkey see monkey do, now they all keep jumping out. Will clipping their wings keep them from jumping out? I really can't have them pooping all over the garage.
