First and foremost I am sorry for your losses
its terrible.
I live in the country, and my neighbors own hound dogs (theres about 10 beagles (rabbit dogs) and 20 + walker and coon dogs between 3 neighbors) - all live right by me.
Me and my neighbors have an understanding. If one of the dogs is loose and not causing issues with my dogs or by the chicken pens (my coops are locked tight at night so i don't worry about dogs getting to them except 1 who refuses to sleep in a coop) I let them be, but if the dog (or sometimes dogs) are still around in the AM when I go to let the chickens out - I will fire off a warning shot at the dogs to send them home if they go near my pens. If the neighbors don't come get the dog then its going to wind up dead. Simple. Since we came to this understanding I have only fired 2 warning shots at the dogs - haven't killed any of them.....yet. My oldest neighbor told me he's done the same - his boys live beside me, and he's shot one of their walker hounds for raiding his coop, he owns chickens, guineas, and turkeys. He won't stand for a chicken killer.
My advice : make sure your mom wakes you up next time. If they are in the pen, if they are friendly - you got 2 options : Take them to the pound, or pain X's on their hips/butts and send them home. However since the neighbors seem to be unlawful irresponsible citizens I'd just take the dogs to the pound. Or if you want to try scare tactics, if you have a gun, when the dogs are in your hard pop off a few shots near them into the ground to scare the devil out of them.
But honestly getting rid of them by taking them to the pound or SSS (shoot, shovel, shut-up) is going to be your best bet. If they do leave for now, they'll be back later on and again and again and again. These dogs haven't had rabies shots so who is to say they don't tangle with a rabied raccoon and then come into your yard - and bite you or one of your family ??
Good luck
