I have been hunting coyotes on a sheep farm near Manchester for the last 5 years. You are never done with it. They will constantly change their tactics and you will end up interacting with members from several different "clans" which may do things in a totally different way, based on the experience of the alpha.
There are specialist "no-climb" fence products out there which are welded instead of woven and the vertical strands are close enough together to make it basically impossible to get a decent foothold. I have seen it used in Colorado to provide protection for Alpacas. Even then, there were several alternating hot wires in front of the barrier a couple feet with a high energy energizer with a higher frequency rate which makes it basically impossible for a predator to get through without being hit a few times. This is often needed for black bear which can be very persistent and can even learn to tell if the fence is energised without touching it.
So, if this is a long term plan (keeping defenceless livestock), you are going to need good fencing first and then you are going to need a well maintained electric barrier around that which is sufficiently fast to prevent it from being breached.
The history of the sheep farm I help out on: Prior to getting involved, they lost the majority of their lambs and up to 1/4 of the breed herd (about 75-100 ewes total) during summer daylight raids. In the winter, spring and fall it would be attacks at night including some at first and last light. I hunted them primarily at first light until I killed the boldest ones and they retreated farther and farther from the barn where the sheep sleep at night and where the great pyrenees has a "circle of influence". There are too many coyotes active at night for even such a large dog to have free movement. Once that point had been reached, most of the activity was either nocturnal or during the day in summer when I am at work. I invested quite a lot of money in a 3rd gen NV scope and started hunting them at night. After killing a few at night, we went several months with minimal activity. But don't count on it, if one group of coyotes gets "educated" and moves out, another group will quickly move in. This was all on a 120 acre property which has several hollows the coyotes can move in without being readily observed unless you are out in the field.
We have not had much snow this year, so that makes tracking them and determining their movements difficult. This is best done first thing in the morning before animals on the farm become active.
If you need any advice or help, send me a PM here on the forum. I am located near Napoleon.
I put some trail cams around the pen and haven't seen one yet... I know they're around. Around deer season I heard barking and yipping near my house. I went out the next day and found this..

Anybody think a couple strands of barbed wire on top my 6' fence would keep them from climbing over? As soon as the ground thaws I'll bury some fence around the pen.
