I'd say get the 2 roos, and then pick which will be the one to keep... Siince you will be getting as chicks, they'll get along for a while, but then you will have one become the dominant roo... SO, when they hit about 6 months or so, then would be the time to pick the one you want to keep and freezer camp the other, or rehome him. I have 12. 2 for my silkie roo, 2 for my bantam mutt, and 8 for my big guy. The silkies and the mutts are young enough yet to not be a problem for my big roo. But come spring, they'll be seperated out and into their own coops and pens.
