I've lost 5 hens in the last two weeks and i just wanted to see if the predator that i think is doing it is correct? What I noticed on each kill it dismembers the head and a wing then feeds on the body. I'm thinking it's a possum. The last one was killed in the coop and it was closed. The only opening is a triangle shape hole on the peak top. It is big enough for for something to get in, but for the last 2 years never had issues till now. This pest has made a habit so going to seal up those triangles and get a trap. I'm guessing possums climb? Since that's the only way it could get in. There are no holes in the ground or the fence is not damaged. So is it a possum?
