My plan is to line a stall with 1/2 inch mesh top to bottom and then tuck it under the stall mats all around the bottom where the floor and walls meet. I would add straw to the floor to cover the mats. There is a door the goes outside where I'd like to add a big outdoor flight pen. Would I even need a flight pen if the stall is pretty big? I'm only looking at housing 60-100 Bobwhites in there. Does this sound like it would work?
