And if it is coons, you'll know it shortly, because they will be back, That new fence will not keep them out. Not only can the coon walk right through it, he can dig under if need be. You have to fence the ground out two feet also. Here is what I had to do> Doubled hog fence (as he has in the pic) crossing each link in the middle then wired together... Then barn tin for ground cover.... Also, note the intended ground level ventilation factor built in.. Just cover with a drop tarp in the cold of winter. I thought penning chickens would be a cake walk and I found out quickly that toothy predators lurk in the night, and if you want to keep the same chickens for a long time you'd better have a helluva solid coop.
