The sketch in the SOP shows a pea comb well from the angle it is drawn, but it doesn't show that it should lay along the curve the the head. I see so many that stick up in the back to a point, and that is something that really turns me off. I try to keep the ones that remain tight and the middle row straight. My hardest thing to get is with no curve at the bottom. It isn't significant on the birds I select, but for combs, that is what I am working to fix on them.
spend some time with breeders of ameraucanas and brahmas. you learn pretty quick that a pea can take many shapes, and each individual has a preference. ill get a shot of my three males. show you how varied combs can be and what i prefer.
