My EE and Speckled Sussex are laying some big eggs and are the same size as large eggs at the local grocery store....my Maran however is laying eggs that do not even fit in the egg carton. she lays one every other day....and their gigantic!! She has been laying for over a month now. Body size wise, she is much larger than the rest of the flock consisting of all standard breeds...Speckled Sussex, Barred Rock, EE, Welsummer and Silver Laced Wyandotte. She is about 8 or 9 pounds. Any chance she will continue to lay XXXXL eggs in the future cause if so, i am gonna have to buy some different egg cartons or cut the tops out for some of her eggs so they will fit.
