Chick with curled wing feathers

The frizzling gene itself is a partial dominant, so typically a parent would have to actually be frizzled in order to make frizzled offspring.

However, there is a recessive 'frizzle modifier' gene, mf, that tones down the appearance of frizzling so that a bird expressing the modifier (mf/mf) and one copy of frizzling (F/f+) looks normal or mostly normal with just a little bit of raising on feathers in some spots. If a bird that is F/f+ mf/mf is bred to a normal bird, f+/f+ Mf+/Mf+ or f+/f+ Mf+/mf, then you'd see some frizzles in the offspring despite the parents not outwardly looking frizzled. That could be what's happening here.
