Has anyone ever come across a lime green egg white in a duck egg? One of my duck egg customers came across this & asked me about it. In the 6 years I have been raising ducks this is the only time I have come across this so I was not able to answer her. Concerned the egg is not safe to eat with this issue. Any idea as to what would cause this? My duck breeds are Khaki Campbell, Golden 300 Hybrid & Welsh Harlequin.
