I'm fairly new at this chicken venture and I seem to take everyone at their word, b/c i don't know any difference. We have been buying eggs and chicks from a local chicken farmer/friend. Living in redneck country, nobody calls anything by it's real name, we have Yellow Buffs. OK....... Everyone calls them Yellow Buffs. I decided on my own they must be buff orpingtons right. They look like buff orpintons... Then I started researching and found Buff Plymouth Rocks, they look a lot alike, and this guy raises, RIR, BR and sex-linked. I guess I just need to ask him what they are, but my hubby is the one who deals with him and he will never remember to ask. Is there a surefire way to tell the difference? I bought buff orpington chicks from the hatchery, so i know what they are, but I still have 8 from this other guy that I'm second guessing, b/c they are "yellow buffs".
