The only ways ive ever trapped coon is to take a cage trap and sip zie an open can of sardines to the back end of it and put it where ur coop is at night. on the outside of course of ur coop. Another way. I drilled a hole in a log about as wide as two of my fingures. Hammerd nails in to the hole in an angle. Put a bit of hotdog in the hole. ( the coon sticks its paw in it to get hotdog and then cant get it out cause of the nails. And then the easy way , Leghold trap. Find where its been diggin and just pop it there. Or where it entered in ur coop. Just make sure ur chickens dont get to it. (imagine a chicken pecking it.... snap neck). Ive caught over 7 opposums and 3 coons with leghold and cage traps just this summer.
