I know back in the late 70's or early 80's there were people killed by "wild dogs" in KY. I am sure I have read news stories since then. A forester I know was treed by wild dogs when he was cruising some woods. They kept him in the tree for hours before they left.
I was talking to an old farmer years ago. He was selling the house he was born in and the land. The house was built in 1905 or 1895 by his Pa. The Farmall they bought midc entury was still on the place and worked.

The farmer raised chickens. He and his truck was REEKED of chicken poo.

Interesting man to talk to if you were up wind of him and not in his truck.
He said back in the day the area farmers would have to get together and go wild dog hunting. The number of wild dogs would get to a point that they were starting to take down too much lifestock and become a danger to people.
I have seen dogs and coyotes on my land. They have to leave if they see me.

My Place. My Rules. If they don't leave I have to Shoot, Shovel, and Shut Up.

I have young kids so there is no choice. So far, the dogs and the one coyote I have seen have left as asked.
What the OP describes is very dangerous. The dogs needed to be killed. No if, ands, or buts. Either find someone you know and trust with a firearm to help you out or go buy a good centerfire rifle in .223 or larger. Practice with it. Since you know why the dogs are on you land I would start baiting them further away from the house. Maybe in couple of places.
Pace off the distance to where you are baiting. Make the distance the same to all you bait stations. Practice shooting at that range somewhere else on your land or on a range. Setting up the bait stations moves them a bit away from your house and gives you a bit of time to practice. Just be sure you have a good backstop. Center fire and even .22 LR rounds can travel a good distance.
Most critters dont look up since that is not where threats for them go from so see if you can set up a blind up high. If you have a two story house that could work. Just dont have the muzzle in the house if you fire.

I have a roof I can easily and safely climb. That was going to be my blind if the coyote kept appearing. He moved off or someone else killed him. Put the blind in a spot so that you can get to the blind unseen/unheard from the bait station.
