-collect and save them to give away to your neighbors, friends etc.
-cook and feed them back to your chickens, they're an excellent source of protein.
-or if you're certain your pullet is broody (she hisses when you come near the nest, she sits all day and night with only short breaks to eat and drink, and she has quit laying any more eggs) then you could let her finish hatching them, it takes 21 days of incubation. But if she's not dedicated you need to collect the eggs so they don't go bad.
Your cockerels may get along fine for many more months, but it's likely your pullet could get overbred and lose feathers, and maybe become stressed or terrified of the boys over time. Experienced breeders have had success keeping a 1:1 ratio (mating pair) but the usual ratio is 1:10 for fertility. It really depends on the temperament of your cockerel(s), some are nice and others are unmanageable, you won't really know for sure until about 1 year of age. Often times, cockerels can get along fine without females present, but if there's not enough to go around, there can be trouble. I personally wouldn't keep a rooster in a small flock (less than 10).
