My arucana hen's(Henny Penny)first egg was HUGE and had two yolks in it. She has laid 3 double yolked eggs total. Now she is laying regular single yolked eggs. She shows she wants to lay but ends up not laying that day when she is going to lay a double yolked egg. Usually the next day she ends up laying a big egg. Do arucanas normally lay double-yolked eggs a lot?
