Was given a rooster..now what.

Well, I was given a rooster, I already have a bunch i dont need and was going to process them soon, but hes very pretty and was free from the neighbor. I have him seperated right now (Hes also apparently very good at crowing) Hes much older than my other roosters. I'm afraid to put him in with the other chickens, Because i think he'll end up fighting with them. I kinda want to breed him though, but am unsure of his breed.

Also, i was getting an egg a day, for about two-three days, and now i havent found on in about 2 days, should i be worried?
