I agree the fox will be back. They have a secure night time house. But now we are going to build a secure run for them. The advice I was given was they were too alert and too big for a fox during the day. Clearly not the case. So we are working on plans for a run and tractor.
You know a confining coop for geese really isn't going to work well because geese are roamers, much more than ducks or chickens.
I'm thinking an electric fence system would work better for geese, because by very nature they need more room and big swaths of grass.
I hope this helps some.
