Here is a picture of one of my Call Duck yolks. I cracked open 2 to see if they were fertile, this one was the bigger of the two. I have 2 hens and a drake. There are 9 eggs but neither will sit. It's their first year laying. I'm assuming if this one is fertile then most likely they all are. I put one in the incubator a month ago but it never grew viens. Does this look fertile to y'all? Thank you!
