Hi, I have two light brahmas from the same hatch date. Both are supposed to be pullets. One has developed pink/red in her comb while the other remains light yellow. The one with a pink comb is taller, holds her head up high, and has longer tail feathers. What do you think? Is one a roo? if you click on the photos they get bigger. The red/pink color didn't show up that well, but you can still see that they're different.
