Last week a fox attacked one of my hens while they were out foraging. Happened in the middle of the day while both husband and I were out doing work in the yard. Thankfully we were out because I was able to hear her cry and stop the attack. She was pretty chewed up and had several deep puncture wounds. Our neighbor is a vet so I took her across the road to have her looked at. She got her cleaned up and gave her some injections but we just had to wait and see how she recovered. We kept her in chicken ICU for about 6 days inside the house and she did great! The vet said she looked good enough to go back out to the coop. We only have the 2 hens remaining at this point (my original 6 are all gone due to hawks or natural causes (they were 7)). The hen that wasn't attacked was hatched with the one that was and they had never been separated before this. While the one was recovering inside the house, the other one was crowing and seemed quite stressed being alone...so I was beyond surprised by her behavior when I brought the other back to the coop. There was an initial stand-off that I had assumed was her confirming who this "new" girl was but she immediately chased her down and began pecking her. I didn't know if it was them re-establishing the pecking order but it continued to happen all afternoon, to the point that the recovering hen, Foxy, was being knocked down and continued to be pecked. It looks very much like introducing new pullets to the flock. I'm not sure what to do with them. Foxy can get away but I'm worried that she's not "fully" healed yet and it will stress her more. After surviving a fox attack I don't want her to deteriorate from the stress of the other hen. I'm super surprised that this is even an issue because she's not a new hen and they have been together their whole lives! They have always been the outcasts from the rest of the flock because they came in just the two of them. When the last original hen died, nothing changed with their behavior at all. They just kept to themselves, so again I was not expecting this! Any thoughts?
