Hogs go where they want to. LOL. They are wily enough to evade many traps and about the only way to handle them is to have a hog hunt every few years. Or a bad drought. A neighbor organizes a hunt every few years, gets permission from all neighbors to cut fences and repair them in order to make a clean sweep of the area. It has been successful so far. The fences are well mended after they have been through. They make sure livestock are not disturbed and they clean up after themselves. All we have to do is keep the dog penned up when they go through.
Armadillos are something we have to live with. Every so often they come through and leave the yard pockmarked, but they get the grubs buried in the ground. So over all I figure that's a good trade.
We have a dog who is very possessive about her cattle and she does chase the coyotes away, but at night they still hang around. Blue is larger than most coyotes and our cats are indoor only. I have spoken with several area vets about coyotes. Their consensus is that as long as the newborn calves are healthy, coyotes won't bother them. If they are sickly, left for long periods of time by their mother or can't move around much (We have a one week old bull calf whose front legs are slightly bowed and haven't straightened out yet. We are keeping him and his mom close to the house until he is able to run without falling.), then they are in danger.
Sheep and goats are another matter. Small pets are also in danger. Donkeys may be OK as long as you have only one. However, I was warned that they are perfectly capable of killing calves or other young. I don't think that it is done intentionally, but in an effort to keep them away from a "potential enemy" even if that enemy is us.
