Help me settle a bet

I say that chicks hatched from 7 days' worth of eggs from 3 hens covered by 2 roos can be fathered by either of the guys; Bill says that's impossible. Who wins?

You do.
Given that both roos are on all the hens and not just sticking to their favorites.
At the proper time of fertilization during the egg process either one roo or the other will have the dominant sperm.
Given that you have 7 days of egg collecting you are pretty much assured that you should have offspring from both roos.. unless one roo is infertile or they stick to some very strange exacting mounting schedule.
