When we sell our eggs are customers like a nice variety of color. We have white leghorns and though they lay well during spring and summer, in the colder winter months they really slack off and just spend all day sitting on the perch, fluffed up while my other birds- Rhode Island Reds, Speckled Sussex, and Chanticleer hens do just fine. Does anyone have a breed that lays white eggs and is cold hardy ???
