Well, well, well... Yesterday morning I candled and was amazed to see three eggs definitely veined and developing.

Two more had early development but apparent blood rings.

The sixth one was a double yolk with no development at all. Ah well, 50% viability is pretty impressive. I decided to candle one more time this afternoon before removing the early quitters.
But wait, what’s this? The blood rings weren’t blood rings at all! There are now
five clearly veined, developing duck embryos in the incubator.

I can’t wait to see what happens with these eggs.
