We recently had a fox that took out 14 of our chickens. We have 2 Jersey Giants that were nesting that he didn't get. They have has 2 sets of hatchlings in the past so they are not first time moms. They have been very good mothers and very protective. The eggs started hatching from "Dolly" yesterday and I saw the chick layed aside, cold and put it under her. I noticed another pecking out of it's shell. I checked shortly after, and Dolly had blood on her face and was eating the baby chick alive. She had eaten out it's stomach and it was still chirping. We killed it. I took the other one that was hatching and put it under Carrie. When it hatched out, I caught her eating it. She had eaten the scalp off of it and was about to start on the stomach. I have it in "intensive care" in my garage and it appears that it is going to be fine. This morning, I saw a half eaten one in Carrie's nest with blood all over her face. I have removed all eggs and put them in an incubator. Has anyone else had this problem before? Why are they doing this? Is it possible that they are killing the chicks before the fox can? I didn't think they were that smart. lol Any help would be appreciated. They have always been wonderful surrogate mothers and I hate to get rid of them but cannot have this happening.
