I thought I had barred rock chicks from tsc (use Ideal i think) until I got very white small eggs. I really didn't know anything about Barred Hollands and was disappointed not to have big brown eggs. I'd like to hear more about them from the folks who know: YOU! Are they endangered? How well do they lay? All ETC.s welcome! Mine lay a small white egg and seem to be every other day layers. They are new layers.
