I agree, pullet.
I've had lots of pullets with one curvish tail feather.
Roosters have all their tail feathers curving, with pointy saddle feathers, with fleshier comb and wattles.
This bird has neither comb or wattles, no pointy saddle feathers, but one slightly curved tail feather.
Other than some yellow on the wing bows, but also matched elsewhere, I think you've got a pullet.
