Ok, so I just went out to collect my eggs. I looked in the nest box and at first I thought my EE who started laying green eggs last week had a blip in her egg painting system. Then I picked up the egg. It felt funny. Duck egg finally! My question is, I just got a drake last week. I haven't seen them doing the deed yet, but they have plenty of time to themselves so they could be. Once he does, how long until the eggs are fertile? How can I tell? Is there a bullseye like chicken eggs? Thanks!!! Duck egg is top left.
