Is this one you got from me? Looks like one of mine

Without seeing the tail feathers I don't know for sure...but I'm also guessing Rooster. It's sometimes hard on these guys though. The body posture (sp?) of the girls is just as upright as the boys. Is the comb a pale pink or redish? I'll have to get a good shot of my lil' Reggie the rooster...he's 100% boy!
Nope, they get the white on thier chest and as their feathers come in they lose all the white on thier chest for speckles all over thier body. Like I said above you can't tell by body posture...you have to go by the color of the comb for the most part. If it's a pale pink and relatively short (like up and down...not tip to tip) it's a pullet. I'll try to snap a picture of a young pullet and a young cockerel for you guys.
