Relaxed Farming - our farm in your classroom

The worry about the fox continues as we caught one prowling at 8am this morning! We had taken the goats down to their paddock and were filling up the hay racks when there was a sudden commotion. The goats ran out of their house onto the decking and a fox proceeded to run from behind their house, up the bank and out into the copse beyond. We think the goats scared the fox and the fox scared the goats!!! Meanwhile none of the birds in the poultry enclosure seemed to have been alerted as all was calm and there were no shrieks or alarm calls.
We wandered back into their paddock and wondered how on earth we could protect our poultry. Their fence is a mere four foot high (and many regularly jump/flap over it) and with a high bank running along one side, it would have to be at least 20 foot high to stop anything leaping straight in. We used to run an electric fence all the way round but that has long since given up the ghost (a good half of it is now so entrenched in the vegetation, we can no longer even remove it!!). The fox scarers (devises that emit a high pitched noise) no longer seem to be working either.
Some of the birds do demonstrate natural 'fox-proof' behaviour such as our merry band of Muscovies who are such able flyers that the chicken house roof is an easy escape for them. The turkeys can gain height too but not quite so fast or elegantly. Geese are known to chase foxes sometimes but the fox needs to be timid and the geese very aggressive, and not sure we have this combination. And as for the chickens, when it comes to 'fright or flight' we think a great many of ours will adopt the former which basically means they freeze in fear: NOT a 'fox-proof' position at all!!!!
