The comb thing confuses a lot of folks, don't feel bad. It's the reason we always ask the age of the bird. If your bird were, say 6 months old, we'd probably be saying pullet. But at only 3 months, that's way too soon for a red comb no matter the breed. Plus, looking at the neck,can you see some of the feathers are getting that longer, pointy, kind of glossy look? Those are hackle feathers, they'll continue to grow and saddle feathers will come soon. Those are male traits.
If you just got the bird, and it was sold as a pullet, contact the seller and return the bird or get a refund. It's not what you paid for.
