I agree that building a bachelor coop is the best option. If she plans to have them breed, giving them away or sending them to chicken heaven will just be a temporary solution to a permanent problem. She could rehome all but one for now but then if they breed again...it's a 50/50 shot for a boy or a girl...and then you be right back where you started. A bachelor coop will eliminate the OPs current AND future predicamentBy my count, you've got 5 roosters and 5 hens. You've also got 3 older hens bullying 2 younger hens. Am I right?
I suggest you put the younger hens in the quarantine pen, the older hens in your main pen, and the roosters somewhere else. It sounds like the quarantine pen adjoins the main pen, so the different ages of hens can get used to each other.
For the roosters: you need another pen, since you either can't or won't butcher/kill them or give them away. (Lots of people advise killing them because some of us like to eat chicken, and because it's an "easy" fix--you never again have to make decisions about those particular birds.)
Several people had ideas for quick coops. Here's another: chain link dog run (several panels that fasten together), plus a doghouse or similar inside for bad weather. This is not be a predator proof setup, but could be a quick way to keep the chickens from killing each other while you figure out something better.
