Oh thank you guys!
I don't have the means or expertise to go trapping a fox.....I don't think my neighbours and I are as rural as most of you! My chickens are the nearest thing to country living I've experienced! The only thing I can really do (and have been doing dilligently) Is to fox-proof the garden and the chicken shed. It's got new bolts, doors, latches etc etc.
My Daughter and I are really, really excited about getting our ex-bats. Will be a totally different experience from raising our last flock, but we always were suckers for a sob story!
