No wattles yet! But one thing is that its quite aggressive when you first go in the pen... s/he likes to attack my hand! It's quite cockerel like behaviour but then I wonder could that be to do with being a single chick. I thought the same... that the head looked like a pullet but I just hope its not because its a frizzle making what would be a flatter crest into a more upright one.
Thanks for the replies
Behavior, especially in chicks, is no indication of sex. I see pullets chest bumping all the time. I have a trio in a building and when I let them out, you would think the two hens were the roosters and vice versa with the rooster.
I'll have both pullet and cockerel chicks peck at me when I pick them up.
I think its a girl! After much waiting, there is no sign of a comb or wattles at all. Still doesn't get on with any other chickens tho... very much a mummy's chick haha! I will try and get a pic soon if she will stand still long enough!
