Today, the hens went missing. Shortly before this happened, I saw a feral cat that I chased away. All day, they were hiding somewhere. Could not find them and could not entice with my treat noise. Hours later, a very shaken bird is in the driveway ALONE. She was shaken, and it is not like her to be alone. Later, I go out and do the treat shake, and 7 come out. (I have 8). Then a few hours later, those 7 go to roost and one is missing. I am sure she is not sitting on a clutch as she is not laying yet, and her comb was nice and pale today, so not about to lay either. I have searched everywhere, and I see no feathers and no carcass. It is hard to see in the thick brush, but I don't see anything. When I was looking, I did see a freshly dug hole in the ground where they like to range. Neighbor says he sees ground hogs in that area. She is about 25-28ish weeks old. Would a cat drag away the body? Do you think it was that feral cat? Could it be a ground hog? Is it possible I saw a fox hole? Could it be that? We have hawks galore, and we had a scare a week ago, but I think she is too heavy for a hawk to carry away and there is no evidence with no carcass. What did this? Help?
