So my First Chicks are 3+ weeks old now, and I'm starting to have some clues that some are boys. So here they are: The Rhode Island Reds Peppercorn (suspected rooster?) Another RIR chick for comparison (both of the other two are developing very similarly) I have no clue what the three silver laced wynadottes are, so here's all three. Topaz. And Yes, (s)he has a single comb rather than the standard kind. In the two days since this picture his/her comb has gotten more pink and redish wattles have appeared. Diamond C.Z. I'm also curious about these two, but they're bantams so I don't know if they're big enough to tell yet! Batman (unknown breed, maybe Japanese Bantam? If you know the breed that'd be awesome to know too!) Acorn (Silver duckwing OEGB) In the past days comb has grown a touch and wattles are starting to show. I think this one may be a boy too. I also have some silkies, but I don't think it's any point trying to sex them at 3 weeks. they're all too similar at this age. Anyway, thanks for any opinions or guesses!
