It would really help If you took a photo of him/her with the tail. You not only have to look at the comb but also the tail. Very pretty chicken though!
So far "pullet" has most votes. She is still young though & i am seeing that quite a few people end up with "sneaky roos"...so im trying so hard to just wait it out. So far, besides appearance, behaviour wise this chick isnt showing any roo signs.
The one we now know is a roo, is leaving us today. While he is ok with the 2 chicks his age, he is rather nasty with the older girls, & they dont enjoy him being around.
