Since having my own chickens it continues to amaze me how they get the store-boughts so uniform! on the left, duck egg from Helga, my Welsh duck who started laying about a month ago. middle is from one of the 7 month old buff orpingtons....holy cow...bigger than the duck egg. on the right, first egg from one of the babies (5 months old). I think it is Jackie's...a barred rock. and inside....top is duck egg. botttom, a double yolker from the BO egg!
