I'm a moron. I KNEW I should've marked the eggs but nooo I thought hey, there's only a few, I'll remember which ones are which. Except someone else, or maybe the same duck, is laying in the nest - and they're fertile eggs. All of them. Now there's nine. I'm worried since the hen has been incubating some eggs for a week now and one was plunked in today for her. I wish I had marked them!!! GGAAAHHH I even said I was gonna mark them when there was only two there! I was thinking of waiting until tonight, candling them and seeing their progress and marking the older ones vs. the newer ones.... but then what? She's already started incubation. Will the poor things still hatch around the same time or will I be placing the last few in an incubator during lockdown? Mark. Eggs. In. Future. Now I know.
