Can I keep two roosters with thirteen hens

[Abriana]

I have 5 roosters right now and usually have 7 to 10. 4 of them are confined with the hens in their building right now since it is zero outside. Each of these males have their own harem of hens and I rarely see skirmishes between them. So it's possible that your two will get along. It all depends on the personality of the young rooster. If he is willing to accept his place in the male pecking order then life will be good. If hormones get the best of him and he wants to be top rooster then you will have to decide which one to keep. I usually only keep roosters that don't become aggressive. And any breed of rooster can be good or bad.
At 6 months old you will know soon if it is going to work out having 2 roos. I hope it does for you.

He is a little over six months now and still sweet as candy

Most of the problems I've had with young roosters usually happens in the 4 to 5 month old range. You may just luck out and have a keeper!

so I have a cockerel named chickie. When he hatched, I thought he was a hen, but he wasn’t, and he was the only one to hatch. I knew I’d have to rehome him, so I didn’t give him a name. I referred to him as the chick, and soon affectionately as chickie and it stuck. He is six months old and the sweetest thing you’ll ever meet. He asks to be picked up, he follows bantam his mama around and runs with his head down and butt in the air which is tooooooo cute. He trusts me and I love him and I just can’t give him up. So here is my plan, i keep young chickiedoodles in the run until his crazy cockerel stage has passed (hasn’t even started at all yet) and then I use a nail file and keep his Spurs real short. Then I duct tape my grown cocks Spurs so he can’t hurt him. Chickie is very submissive and I don’t think Napoleon will attack him. But I wanted to ask about this here.
Also how old is too old to be castrated?

Well, I keep three roosters (Bantam cochin, chantecler, and welsumer) with my 13 hens, and they get along just fine. There WAS a bit of blood at the start, but once the pecking order was established, they stopped fighting. From what I've read, the rate of survival for caponizing isn't that great, and many people don't consider it humane. If you want to keep Chickie, then just let the "Crazy cockerel stage" pass, then I think he'll get along with the other rooster. Beware, though. I have naturally gentle roosters, and your roo may not be the same.
(Chickie sounds like a great rooster, though! Reminds me of my beloved rooster, Guardian..)
