Fox in the Hen House

Well, the fox was back, took out another chicken, right in the front yard, with Maggie the Golden, sitting on the porch. I seen him go off down through the ravine and up the ridge on the other side, Maggie gave chase, but of course, she didn't catch that darn fox! We are down to 7 hens now. I am so upset, not sure what to do, I hate to keep offering my chickens as fox food. I love my chickens and have raised them from eggs. Another stress from living in the woods. Please Pray for me and my chickens and that we can get rid of the fox.
