Put an ad for them on Craigslist or similar. Sell them, give them away, whatever. You could keep them another few months and butcher them, but I don't see them having an appreciable amount of meat.
next time you're ready to buy birds, feel free to post pics here before you purchase them. We usually can't sex day old chicks--some breeds, but not most. But at 5 weeks we can usually give you a pretty good idea of what gender the bird is. Might keep you from making another purchase you regret!
