Cool. Which is why CCL is a little like the leghorn with their feed input conversion.
Not that they are as high in production but for the inputs given.
I have another OE that was sired by a Splash Marans that has a single comb. Olivia is an f2, being 3/4 Marans, 1/4 Ameracauna. Hoping for olive and avocado green eggs :)
