What kind of chicken is this? Or is it a rooster?

What does the cream gene do? For the crest, I was just wondering if poor quality sometimes lessens that? Just learning.

The cream gene dilutes a legbar’s color. I could see a hatchery quality legbar lacking a crest, but I doubt it would lack barring and cream too.

Both are pullets, Light Brown Leghorn and second a Welsummer

Agreed.
