Thank you everyone for all the advice and ideas!

Last night I was short on time, so I just added some water to her feed until it was soupy and kind of had to force feed her with a dropper. I had to make her drink as well--I think she is very dehydrated. But, she's still alive and kicking as of this morning, though still not getting around much, and not trying to eat or drink on her own from what I can see.
We ended up moving her away from the other 2 hens she normally lives with and putting her in with Polly, our new hen, because one of them is starting to pick on her. I'm thinking that I might just move her into the house like framing fowl suggested, I can get a big box from work to keep her in. Tonight I'm going to make a mash for her to eat, and I will definately add the egg yolk. I don't have any dog food though, but I have cat food, not sure if that's a good substitute?
Rhettsgreygal, our city council has talked about addressing the concealed carry law in the city ordinances, but I'm not sure if they ever got anything hammered out. I know my husband is talking about getting a concealed carry permit, but I don't think I will. I have fired his handgun, and it's pretty big and heavy (but it was awesome shooting it!), so I would need a smaller one if I really wanted to actually accurately hit anything. I did find our bb gun however, so if those dogs come back, they will get shot in the behind (if my aim is true enough

)! I still have no clue whose dogs they were, and they haven't been back since that I've seen--knock on wood.
But, on a better note, my soaked-flour bread that I made last night turned out great! It has a couple tablespoons of millet in it, which gives it a nice little crunch, very yummy. I think I will post the recipe when I get the chance.
