personally this isn't my problem, its my friends.she is having major problems with possums. she left a camera out and caught them on tape sneeking into her coop. her rooster does a good job fighting it off but it managed to kill 4 of her bantoms so far. also its getting her other bantoms sick and she only has one left out of 8! i feel really bad for her and her bannies so i was gunna offer to help fix her coop. but would it be better to just get rid of the possom all together or fix the coop? also, how would i fix the coop? like what kind if wire fencing should i use and what structure keeps them out the best, a box like structure or dug into the ground?
