I don't know what to do after a dog attack

[BellePoule]

My free ranging flock was attacked last night. I worked late, so a friend came by and put them to bed, but didn't tell me 'til this morning that something (I'm guessing neighbors dogs) injured 2 of them. Another 2 were missing, but one was chilling by the coop when I went out there to feed.
One of my 8 week Cuckoo Marans looks like she has all the skin on the back of her neck removed and one of her wings is bloody and hanging, as well as several patches of feathers pulled out and some possible puncture wounds. When I was checking her over, I also noticed that she already as a serious maggot infestation. I'm thinking I should put her down.
My other injured one is an 8 week old barred rock. She's limping and I discovered a bad cut around her vent and a very serious maggot infestation on and around it. Should she be put down also?
I don't want them to suffer any more than they have, but I'm not sure I can get rid of all the maggots, much less them surviving their injuries.

What did you decide to do? The maggots took over that quickly? Can you wash her to get rid of them - maybe with a saline solution? I would definitely isolate her and tend to the wounds if you haven't already.

I cleaned them up as best I could, isolated them, and gave them some diluted asprin water as well as some amoxicillin. However, the Barred Rock didn't make it through the first night, and the Cuckoo Maran didn't make it through last night.
From what I could get from my friend, she came by later than she said she would and found the chickens laying in the yard. She thought that they were dead, because they weren't moving and they were cover in flies. So she put them in the coop with the others, where I discovered them the next day, alive. We've been having a heat wave, so I suspect that's what caused the acceleration in fly growth.
I'm no longer allowing them to free range without supervision. Their coop is large enough (it's an old 10'x15' storage shed with one wall of wire) for them to stay in when I'm not home.

I'm so sorry for your loss.
Some people just dont get how important chickens can be to us.

Awe.

I had a hen suffer a gaping wound from something and I treated it with Rooster Booster Poultry Wound Spray that I bought from tractor supply. It was big enough that it looked like it needed stitches, but I kept treating it and it finally healed up. I should add that I'm not an expert, I've only had chickens for a year. Sorry about your loss...

I’m so sorry. The whole thing sounds awful.
