I agree, if you have enough hens and a correct size of space then 2 roosters should not cause problems unless they are both very dominantThat’s absolutely not true, it depends on how much space and females there are. If each has eight females, and there’s enough space for both, they wouldn’t have a problem. When one is less dominant, there also aren’t many problems.
I do agree if they’re both dominant, they’re gonna fight.
