I have both.
The RIRs are nosy, friendly, bossy and bold. They think painted toes are food, no matter how many times they are told differently. They knock on the door and ask for snacks. They lay enormous eggs pretty much daily. The roo, even at 4 months was becoming nasty so he had to go.
The BOs are calm, timid, fluffy golden balls. Big Buff is everything you could wish for in a rooster; gentlemanly, protective but not aggressive and beautiful. These girls are consistently laying eggs, even without suppplemental light, and look like mobile balls of sunshine
Both breeds freerange well, and follow me to the snacks.
I join the chant:
Get Both
get both
get both
get both
get both
