What age is the best to rehome an extra rooster?

[Alvie]

After you get rid of two males, you will only have three females left, right?

For adding new females, sooner is probably better than later, if you can get one that is close in age to the current ones. Having the new one be slightly older, rather than slightly younger, will probably make it easier to integrate them (because a slightly older one will be bigger and more confident, less easily bullied by the current three females.)

Thanks, that's great advice.

The two roos (confirmed!) have found a new home. Thanks for everyone's advice
