Erica and her 14 friends were hatched on May 1. From Meyer Hatchery came, as ordered, 3 Golden-laced Wyandottes, 3 black New Jersey Giants and 3 NH Reds. 6 more came alongside in the "brown layer variety pack." Of the six I have an extra Wyandotte, an extra NH Red, a barred Plymouth Rock, a white rock, a RIR, and... Erica, my mystery hen. She is 10-11 weeks old in this pic. Can you tell me her breed? She is beautiful, her brown feathers change color and pattern into the tail. What have I got?
