We have 9 guineas that are 4 months old. They have been raised with our chickens since both were chicks/keets. We have cut an opening about 7 ft high for them to fly out of but apparently this is not working! We have a large open air coop and try not to let our chickens out, hence no ground level door. We're fist timers with any birds so please be kind but informative!! Suggestions? Thanks
