Darbo, i have kept white leghorns, cream legbars, cuckoo marans, light sussex, warrens, all sorts, they all have theyre own qualities, i like the pure white colour of the leghorn eggs, the chocolate dark colour of the marans, the pretty sussex, the layning amount of the warrens etc, but this is the first time i have ever tried black rocks myself, always heard good things about them, but i must say, they beat all the others into a top hat, an egg a day per bird almost, hardly slowed up during the winter, quality of shell is second to none, and apparently will stay so for many years, nice size e
