I am not sure on that. I have heard varying answers. both my barnedeveler x lavender ameraucana crosses produced nice olive eggs and they do not have pea combs so. not 100% sure
I am planning to try a Cream Legbar x Crele Penesedenca back to a Crele Penesedenca. anyone heard of this cross? It will be interesting to see if these auto sex breeds will produce a auto sex chick? regardless should be a stunning bird. Roosters for sure. with a cool spin on the olive egg.
