I have a very small flock compared to some of you (started with only 6). One died awhile ago of a health issue. My husband forgot to close the pen gate at the beginning of this week and we lost one. She just vanished. No trace of her anywhere. So, down to four. This morning I went out to feed and found 2 beheaded and the other two injured in the neck area. One will be okay. I saw blood, but no puncture wounds. The other is missing skin on the top of her neck. I don't think she will make it. There really isn't anything there for me to try and suture. Any ideas? They both are fairly shaken up, but they are eating. They were all securely in their pen when this happened. Something dug under. From what we've read, it seems opossums are the ones that behead and leave. Anyone with opossum experience. Since I am getting chicks to replenish my pen, we are going to get a game camera to verify.
