We have taken the decision to leave the geese out at night as currently, we have no known fox activity (yes, our fingers are crossed) and with ten of them, there is definitely something in the whole 'safety in numbers' idea. When we had a fox attack on Tom, Barbara and Margo back in 2016, the three of them made a hugely valiant effort to chase him off. I expect ten at once might just do it. The geese are very happy not to be herded into the barn each night and of course it means MUCH less mucking out in the mornings for Jack
