Have a great predator proof setup right now. Smallish barn (8 by 8) plus extended, attached run (12 by 24). Would really love to have two barn cats as part of a feral rehoming project. (I know that feral cats are a debatable predator in and of themselves, let's ignore that part here please.) How do you give your barn cats access to the barn and run to come and go as they please without giving the same access to predators? If I mount cat doors high up, open only during day time, there are daytime predators that will get in still, right? People that have barn cats, how do you lock up the coop from predators? What works? I currently don't let the chickens free range unmonitored because we have foxes in the area. They go out twice a day with babysitters but the rest of the time they are locked up to go in between run and barn as they wish. A cat door open during the day would let something in, right? Moreso that what I do now.... ideas....?
