we have a total of 12 hens outside however this morning one of the three silkie’s started to crow so it is obviously now a Roo. There is another of the three silkies that looks just like him and might turn out to be a Roo as well. If that’s the case we can only keep one of them so my question is which of the two do you guys think it’s better? One Roo is substantially bigger than the other so should we keep the bigger or smaller Roo?
