I was sure i was gonna cull him based on the single comb alone, as the breed standard is a rose comb. But his chest coloration is so brilliant, he's the biggest, and he's head to head with Kevin on leading the crowing. But that single comb...
I would like to point out that Single Combs are also found on SQ breeding lines and the Single Comb is entrenched on the Wyandotte breed because Heterozygous Rose comb roosters(R/r+) are indistinguishable from Homozygous Rose comb(R/R).
Homozygous R/R roosters have poor fertility and R/r+ males out-compete them. It's almost certain that your Rose Comb males are R/r+
