Is our hen a Black Orpington or a Black Australorp?

What would happen if they didn't cull the ones who have wrong leg colors? If they kept breeding those birds, would that make the white leg gene spread and eventually take over the whole flock?

Yes, because it's dominant.

Look at Mischief -- a Blue Australorp x California White. He ended up looking like an over-sized Leghorn with white skin and black speckles in his feathering.

It would depend partly on which birds they keep for breeding in later years. They are most likely to end up with a flock that has some white legs and some yellow legs, and produces chicks of both types.

But because the white leg gene is dominant, you would probably see more white legged chicks than yellow legged ones (any chick with one white leg gene and one yellow leg gene will show white legs, but have the chance to produce some chicks with yellow legs. The only chicks that show yellow legs are the ones that inherited the yellow leg gene from both parents.)

We got Mumble back in April 1st of 2020. She's 2 years old now. Could Tractor Supply have possibly gotten a Black Wyandotte from Ideal Poultry mixed in the bins and it just so happens those Black Wyandottes are a strain that don't have yellow legs

Yes. Probably. I have (from ideal) a brahma with pink legs and a floppy comb, a sebright with a single comb, and a welsummer with feathered shanks. I love them all, but they sure aren't up to standard.
Also tractor supply routinely mixes up the birds in their bins.

Makes sense because White is a dominant gene.

I have wyandottes from breeders that have white legs seems more common then yellow

Alright, thanks! Just didn't now if some of the yellow leg gene would pop up later in that situation.

Yes, yellow would probably keep popping up for years, just like single comb (another recessive gene) does keep popping up in rose comb flocks. But you might not see very many yellow legs, just like you don't see very many single combs from most Wyandotte flocks.

I bet this particular TSC buys from Privett and that she's a Black Wyandotte

I have never heard of Privett Hatchery before. Could be a possibility.

They either purchase from there or Welp and this is confirmed. Apparently Welp drop ships from Privett though
