I found this in the coop this morning not in a nesting box but over by the door of the one coop. I have just discovered that I have 1 confirmed female of my 2 Embden geese. Is this possible that this is her first egg or is this just a massive chicken egg? This is right out of the coop so sorry it isn't clean. It measures 3 inches long. this is compared with a very good sized RSL egg. does anyone know what color eggs a Embden goose lays? white or brown? thanks so much in advance!
