Pretty sure this guy's a roo : But's the only one I got, that looks clearly "Roo" ish. 99% sure she's a pullet (the white one, the other one's a purebred cochin who is Rexi's buddy.) (there's mr. Roo , with lucky.) Lucky is on the right - i'm pretty sure she's a girl.
Awesome silkies! How old are they? If they are under like 15 weeks then I agree, the top two look like roosters and Lucky looks like a pullet. In the last picture from left to right I would say (guessing of course): Rooster, pullet, rooster, and then the last three I can't tell from the back. Hope this helps. It's always fun to try to figure out. : )
Our white silkie, was sexed, and is supposed to be a female. Our cochin, i'm pretty sure is also female. All the other silkies were hatched together, except Lucky, and the smallest one, who were both single-hatchlings. None of them act rooster like, except Mr. Roo. lol None of the others have started developing waddles, like him either. My two orange ones are a little "pair" LOL The splash one, i think is a pullet. The other black one, i'm pretty sure is a pullet... (I could be wrong. haha) silkies are so hard to sex. ^.^ I can always tell right away with other breeds, like my cochins.
