I am new here but have had ducks for a while, so am well versed in all the crazy things ducks do from swollowing impossibly large objects to laying shell-less eggs.
anyway this was is new to me and I'm hoping someone can help.
I free-range my ducks daily, and they have full acess to the yard and the woods.and at night they are fed their dinner of layer pellets and locked into their pen.
I found last fall, that a few eggs I tried to eat had very VERY dark almost navy green yolks:/ where as others did not. the eggs with green yolks are as fresh and any other I do not let my eggs sit for more than a few hours, well things had been going good so far this year, lots of good eggs with nice orange yolks, then bam, the other day i had to throw away about 1/2 a dozen because they ALL had green yolks. the yolks are always formed and even have fertile spots on them and they do not smell one bit. but I'm afraid to eat them, because obviously I do not like green eggs...and ham
all the ducks are healthy. no signs of illness what so ever and many are going on 1 and 2 years old.
could all the grass be making the yolks green, I know alot of whatever a duck/chicken eggs can affect the taste and color of the yolk.
could they be eating something in the woods? I've tried a few other forums but everyone was a stumped as I am.
thanks for any help!
