That's really neat! I love seeing so many people with so many varied interests and deep rooted bits of knowledge online. This is very interesting to me. Thank you for sharing!The pea comb gene is represented by P/P in its homozygous form. It is often considered dominant, however, with a trained eye you can tell when it is heterozygous for single comb (P/p+), so it's more correct to consider it incompletely dominant. Therefore I propose the intermediate should be called the "pingle comb." It's less obvious in hens (other than being taller than a pea) but in roosters it is quite obvious and often the center row of peas is much higher than the others

It can sometimes escape detection in females but I noticed your hen's comb is taller than usual.
It's common for Easter Eggers to only be heterozygous for pea comb.
