There was a football game tonight so I was getting home late about 10:00. And when I went out to close up the chickens there was a small opssum running out of our coop which is made inside our barn. It then climbed over my 4 foot square chicken fence and went into a thorn bush. I went and got an air rifle so I could dispatch it and it was still in the bush when i got beck out then i shook the bush so i could get a better shot and it ran. Could a small possum kill 17 week old hens while they are roosting and will it come back again in daylight or in the evening?
