Coyotes will only breed enough to create the pack. They will not over breed where it causes food shortages for the pack. You will never kill them off unless you bounty them. I hunt them year round and kill the h_ _l out of them. I hunt them in 2 states and I can honestly say I have never seen a shortage of them I put them as the smartest game animal in the woods today. That of course is my opinion. You will only get one set up on them and they will never appraoch a set like that again. Bears are becoming more prevealnt out theere but i do not beleive they have the numbers to even the coyote deprivation like the Yote! Sheer Numbers don't add up? I willl give credit to stray dogs, farm dogs etc. I have been known to pop them when they are where they don't belong. Yesy, I have hunting dogs, but they are trained and in check!! Not loose! Coyotes, that is your cu;prit!
