Haven't seen our fox again either. We chased ours on foot also, DH even took a shot at it, but missed. Thankfully, the fox was not successful. We didn't lose any. Yesterday we set up the fiberglass ? fence posts and tied aluminum pie pans to them all along the back of the chicken lot and beyond. As the breeze/wind blows the pans clank against the posts. The sun also shines off of them like mirrors. I also have the cheap whirligigs from the dollar store we stuck in the ground. They are large flower shaped ones. Hopefully this will deter predators. We tried this last year and extended it around our garden and we didn't see fox and the racoons didn't get any of our corn. They have taken most of our corn for several years and this is the first time they haven't gotten any, not 1 ear! We did trap 1 racoon, but no more. I'm not sure if this method is what worked, but it is the only thing we did different. Last year we also put the cheap solar lights down behind the chicken lot. I put two together in different spots and at different levels to resemble predator eyes at night. I've read this works. Like I said, it seemed to work for us last year. Will see if it works this year.
and the OH thread! And, of course, the wonderful world of chickens! They are addicting little boogers. Pretty soon you'll have a long wish list full of breeds and varieties.
