Good morning! Your beautiful bird here is lavender (self blue) and not wheaten.

Looks like a pullet so far. Ameraucana’s pea combs can be a bit tricky. The lighter colored birds such as lavender, white and splash tend to have pinker combs, both male and female, in my experience. This bird is still young though so this can change in the next several weeks.If the comb does not become obvious, then you will have to wait until saddle feathers appear. This happens usually after 12 weeks, but may be a few weeks later.
