Giant Silkie Project.

I'm keeping the normal Walnut comb in my bloodline.

Here are Original Walnut Combs.

Really? All the SQ silkies I’ve seen have small walnut combs. Though I couldn’t tell with some of them due to the large crests.

Yep, I have a link that explains.

This says non-Bearded silkies can't have walnut combs, but my non bearded have Walnuts.

The smaller white silkie in your photos is exactly what that link is talking about:
when a non-bearded silkie has a walnut comb, then it has wattles smaller than the standard calls for.

Genetically, a walnut comb is when a bird has the genes for both rose comb and pea comb. But any chicken that is homozygous (pure) for the pea comb gene has wattles much smaller than they otherwise would be (and smaller than the standard wants, so the bird gets disqualified in a show.)

To meet the standard, a non-bearded silkie needs to have a comb that LOOKS like a walnut, but without the pea comb gene being involved. Or with only one copy of the pea comb gene, so the wattles aren't affected.

Bearded silkies don't have this problem because the beard makes the wattles small too, so the standard already calls for them to have small wattles. No-one cares if those silkies also have the pea comb gene shrinking their wattles.
