I still vote pullet too (and I'm from the Am thread
) Get a good look at it's comb- if you see 3 big rows than it's a boy. If there is just one bigger row in the middle and the side rows aren't really showing, then I think you'll be getting some eggs soon. It's old enough now that a female should have a red somb. All of my male ameraucanas (and I have plenty!) - no matter what color- have lots of obvious pointy saddle feathers by that age, and a big comb.
