I vote rooster. I have a pullet just coming into lay and she is just starting to grow a comb...She looked like she had been dubbed a couple of months ago...I mean nothing there at all put some beak pimples...Lol. And she still doesn't have wattles I can see...She is a very clean faced bird
I'll find a pic of her real quick....
See that? Nothing there at all...she now has a inch high redish streak...so still not anything to speak of, but definitely more than she had...Notice the lack of color as well on her (non) comb
Here's another from the side so you can see that she is absolutely devoid of comb.
And he has a pretty nice hackle coming in...so you need not waffle any longer, that is definitely a rooster.
