One of mine looked like a rooster from a young age due to it's large red comb, but turned out to be a pullet. I think you need to always wait longer on them until they get their adult feathers, they are tricky.
I think I may be in the same situation....
Here are what I thought were my 2 male lav orps. (Now I'm thinking I hatched 7 females & only 1 male.) I nicknamed the male with the gold leakage "Dinner" but DD didn't appreciate my logical name. She calls him "Pretty Boy." She wants to keep him & I must admit, his unusual coloring is getting better looking.
*He's going through the typical, awkward-looking,
chicken on stilts phase.
I sold all the females because what I need is a male. Below is the other one with the large comb & wattles. The body of this lav looks very female and its face is not as dark red as the brother. Both are almost 17 weeks. The confirmed male has gold laced saddle & hackle feathers in addition to thick shanks & red comb/wattles. Is there any chance this lav below could be my future rooster?
Here's our silkie with her 2 chicks. (7 weeks old) Pretty sure since hatch that there's a male & female. Depending on my lav roo situation, I may end up keeping this bllk/lav split male.
... and of course, our good, old, sweet, boy, "Mr Dummy-pants" (blk/lav split) He's too old fertilize the whole flock, so he's in semi-retirement.
