Recently a mystery egg has started making an appearance in our coop. We have four hens right now, Two Ameracanas, one leghorn and a barred rock, the remaining Hen/Rooster is a Bantam. We are getting eggs from all four hens right now, but we have a fifth egg that we can not account for. It is lighter brown in color than the barred rock and bullet shaped. Not only is the shape different from the Barred Rock but it is a much larger egg. The Bantam we believed to be a rooster based on the crowing, his attempts to mate with the other hens and his comb and wattle being larger than expected for a hen. He is about the right age to start laying if he was a she. The only other possibility is one of the other Hens decided to start laying a different shape/color/size of egg than normal, but I do not believe that is possible. Any help in identifying if my Rooster named fluffy is actually a rooster or a gender confused hen would be wonderful.
