I'll second the recommendation for electrified poultry net. I have just about every kind of 4-legged predator here, outside of a bear. I've had this netting/fence up now, close to 4yrs, and no animal walking on the ground has got past it. And it has been tested. I've seen more than a couple of dogs try it. And they don't try it again. I've seen the resident fox, sit and look at the birds, but won't come to within 25' of the fence. They have learned the painful lesson also. The fox were the reason I got the fence to begin with, after a couple of bad daylight attacks. I know there is a healthy population of coons around here. Before I put up the fence, I would find their muddy paw prints on my coop, searching for a way in (Which they never found). I've popped a couple of them trying to rob my garbage cans at night (Those motion activated spotlights come in handy). I started with 300' of the netting. I liked it so much, I have bought 350' more. I use Premier's netting. There are other makes out there, but Premier has proven, to me, to be a good company. You properly install this fence, coons WILL NOT get in.
