Flypen, is this the original pair that produced the pea comb stag you shared a pic of a couple weeks back?

Yes sir, I will not be breeding any of the pea comb pullets or stags unless I have to.

So I am pretty sure your original male was pea comb "PC". Single combs "SC" are homozygous recessive, which means what you see is what you have. A single comb bird carries a copy for SC from the male and female. Pea comb is a little more difficult to discern as it can result from a PC from the male and a SC from the female or visa versa. Or it can be from a PC from the male and a PC from the female. We can guess a little about the original male from the offspring. If the original male only has one PC "gene" (he will appear pea combed) then 25% of his offspring this year will be PC. If the original male has two PC genes(he will appear pea combed), then 50% of the the offspring will be PC and 50% will be SC.

You can use the PC offspring to get single comb birds and we can figure out the percentage if you like. I just need to know roughly what percentage of your chicks from the original pair came pea combed or single combed.

Two single comb birds will not produce any pea comb chicks, but pea comb birds can produce single comb chicks.

Sorry for the lengthy dissertation...

I get weird semi-pea/semi-straight combs, in addition to full pea and full straight.

This is what I consider a semi... as it stands up , but has some wrinkles...

Full pea combs fold over and cover an eye usually

Yes, I get those too, but haven't paid close enough attention to know if I can distinguish heterozygous from homozygous pea combs just by sight. Mate them to a single comb female and count the percentage in the offspring.

You see that type comb pop up in alot of crosses.

Both of the original pair are straight comb and about 50% of the offspring comes pea comb. I'll get a exact head count Friday from the original pair mating this year.

Something is not right. I have seen something like that although way less than 50% show the trait. Is it possible some re-arranging occurred in incubator while sexing eggs based on shape? Following shubin's methodology of course.

No re-arranging takes place in any of my incubators, I haven't made any crosses with the Typewriters and every single egg that has been hatched has come from the original pair. Someone somewhere has added some other type of blue blood to them and unfortunately the only way I could acquire them was to get a brother sister pair. It'll take me a few years but I'll get them coming back the way they should be.

That seems like problem I saw then where not proper pea comb involved.
