I've been taking pics of my pullets' double-yokers, thinking them unusual and pretty cool. THEN, I went over to the U of I's once a week egg sale. There were plats of 2 1/2 dozen double-yoker pullet eggs--there must have been 20 dozen of them, or MORE. Gee whiz! Does anybody know if some breeds are more likely to do this? These eggs were white, but I have bought Welsummer eggs from them before.
