At least 3, probably 4 of our chickens are now laying. Today was the first day I got 2 eggs out of the nesting boxes, and one was not from a Barred Rock hen, so either the Rhode Island Red or one of the Buff Orpingtons is laying now. (No blue or green eggs, so the Ameruacanas aren't laying yet.) One of the Barred Rock hens is now laying full-sized eggs. It's pretty exciting news to us!
