If you aren't going to keep your extra roos for your table, then I'd try to sell them asap for whatever you could get. It certainly wouldn't be worth it to keep/feed them for an entire year for only $5.50 a bird. I don't know who would buy a 1-year-old roo for that much, they really should be processed by 4-5 months.
Even if you don't want to process your own roos, you must face reality -- with a ratio of 1:10 for a good mixed flock, then 90% of all roosters hatched have a job to do at the table rather than in the coop. And it's a good job that they do, and we're grateful for it. Yes, it's a shame when you get one that's exceptionally handsome or personable, but you can be sad to dispatch such an attractive animal or be glad that your meat comes in such a lovely wrapper. There simply isn't room in the world for every rooster to live out his existence as a pet or a flock husband.
That's why I encourage people to insist on keeping only mannerly roosters, and not put up with any aggressive behavior from any of them. With so many calm and well-dispositioned roosters fattening in meat pens, why accept less than perfect behavior from the ones you keep in the flock?
