Works for me too. The English buffs have noticeably smaller combs than US Orps, particularly on the males.The Brits are firm believers in lots of fresh air and sunshine, in a rather harsh climate, that is cold and wet all winter.Part of this comb size is genetic, but I've seen those small combed birds throw large , untidy combs here in the US under different management, even when raised in the North.My situation was the exact reverse of Wynettes. My original trio (Col Plymouth Rocks) came from Canada to NW Georgia (probably a lot like N Tx)....HOT humid summers, winters get cold, but not like Canada cold.
My original trio had small combs, the males and the females. I was concerned that they would become huge here due to the heat. After my 4th yr of breeding them I have seen just a "slight" increase in comb size and moreso on the males than the females. I do all of my hatching in Dec/Jan so the young birds do get exposed to the worst of the Ga winters....that seems to help me finish larger birds AND comb sizes that are not too large
