I'm also new to this, but thought it was worth a try. I have Buff Brahmas and these are our new additions, the Buff Orpingtons. I think I can tell earlier with the Orpingtons, which is male and female as their waddles and combs seem larger, darker, and more prominent. Any guesses? Yes I know these aren't' the best pics, but this was last minute shot at throwing it on here. Also anyone in the Asheville, NC area interested in male Buff Orpingtons, they are for sale. We already have "Fred" the friendly neighborhood rooster.
