We are trying to finalize our setup for our Freedom Rangers that will be arriving end of April. Husband needs to get building and I need to order any necessary supplies. We are looking at a tractor within a Premier PoultryNet yard. I've read some posts about chicks getting through the holes of electric netting and/or some chickens flying over the top. Would these things be a problem with Freedom Rangers? My only other concern is hawks during the day, but I think we are just going to have to take a calculated risk on that to allow the benefit of the greater foraging area. Thanks for any insight!
