weird.every wyandotte I have has a rose comb. Even the mixes have rose combs and they are bred with RIR which have (in my case very large) straight combs. Wonder why you had so much trouble?I was messing around with a flock of columbian wyandottes last year and raised 50+ and some end up having straight combs. It was too much work to get good quality out of the birds i had so i sold all of them.
it would be a wyandotte even if it has a straight comb. So if you breed with other slows, you will end up with more slwsOk i thought it was a Wyandotte cause it looks eggsactly like one but with a single not a rose but watever i got 4 slw pullets so when there older ill breed and see what comes out
