Good point Josh people forget about the female comb because it is not as noticeable as the male.Very good question. Medium compared to what? Well IMO you have to read the whole standard. And also the whole description. It also says close to the head. So if you see a big space between the peas on the comb and the skull, I would call that larger than medium. I am looking for minimal space between well defined peas and 3 straight rows. And the hens should be small but still have 3 defined rows. My feeling is that the females are the key to this. If your female combs are showing any space off the head then I believe they will throw too large a comb in their offspring. Especially the males. I am looking more so at what traits my females are carrying as far as type more so than my males. Not completely but I believe the female is the key. This is all my opinion and only from a few short years of breeding and tons of research. I am no expert bit I believe what Nettie and a few successful breeders have to say. I'm having success in my birds so far in my opinion again.
