I've kept Langshan cocks together without too much drama. The fact that they were brooded together and not a new introduction helps. It ultimately comes down to a case by case assessment. I've kept cocks of other breeds together that shared duties, and others where the non dominate cock had to stay out of the sight of the dominate cock. I agree that ten hens may be too few for two cocks. I think part of the key to successfully keeping two cocks together is enough space and enough hens. Also you don't want your hens overly harassed and in poor feather condition. If you can't provide space try to create visual barriers in the existing space, or giving them at least part of the day out of the run to free range if that is practical.Ok, I have a rooster question and since it's Langshan Roos, I thought I'd ask it here. I'm a new chicken owner with my first flock, 6 RIR pullets and 6 Langshans, 2 of which are Roos. Billy is tha black and Razzle is the blue. Billy is a size larger than Razzle, is an inch or two taller and much bigger around, and much more skittish. Billy will eat from my hand, but won't let me touch him. Razzle will sit in my lap and talk to me and will even look pitiful like I hurt his feelings if I put him down before he's ready to go. My flock of 12 has a pretty good size coop and free range from about noon til bedtime. They are all 18 weeks old and though the girls are not laying yet, quite a few of the pullets are really getting red in the face. The RIRs more than the Langshans, of course.
My question is, will I need to get rid of one of my boys? It would break my heart. I think Billy is the better rooster, as far as protecting the girls and for breeding, but Razzle is just so sweet. And I have seen no sign of fighting between them at all so far. But maybe they are just still not mature enough? I have read you need at least 10 hens per rooster and though I would love to get more girls, I have to convince my husband to add on to the coop first. Lol.
So, is there any way they can coexist long term, or should I start deciding who to find a new home for? Because if I have to do it, I need to do it before I get even more attached. Because I know I should probably keep Billy, but I want Razzle because he's my favorite of all of my flock. Help!
Since you seem to have reasons for keeping both, I would give it a try and watch carefully. My experience is to provide no less than 4 square feet of hen house space per bird and no less than 10 square feet of outdoor space per bird. If you're not at these limits I would consider adding hens.
