I would say potentially at least with the white one. I wouldn't say that for the others. Non-hatchery Brahmas ESPECIALLY overseas tend to have very heavily-feathered legs. There's also a chance that a single comb could pop up since it's recessive, but I would say it's likely that that one has Cochin blood.The two blacks and buff all have pea combs, the white is the only one with a single comb. i thought that was weird but perhaps a normal genetic anomaly, like how sometimes two bords of the same color can produce different colored offspring. Good to know though, that that particular farm possibly(probably?) interbred some cochins with their brahma stock I suppose
