I have 5 laying ducks, 1 Khaki Campell & 4 Golden 300 Hybrids; all female. I also have 5 juvenile ducks, 1/2 Khaki & 1/2 Golden (not sure how much of this is relevant). Anyway, I always collect my eggs every morning. Occasionally, I realized I've missed one, but only by a day or 2. The temps here have been hovering around freezing, so no biggie. I'm in the process of making a cake, cracked my eggs in a separate bowl & out comes one that looks Really Bloody & appears to have an umbilical cord attached! I threw it out, but there is some risidual blood in my mix. Is this ok? I've seen a little blood before, which is no biggie, but this is gross. Also, is it possible that one of my juvenile ducks (around 3 months old) fertilized it? It's too early to tell if anyone of them are male.
