I bought some eggs from a lady that raises Pekins. When I met her she went over the whole spill about how they are better for you and all of that. She then assured me that she had washed the eggs and said that since they are waterfoul the eggs are stained because the "ducks lay them wherever, in the mud and all".
So I have chickens and I know the white eggs get stained some if they lay on manure, etc.
So we tried the eggs the other morning and when I put them up to my mouth I could smell a distinctive smell, not sour or anything bad, but off if you know what I mean. I ate the eggs and they were good but they did have the same off type taste. Not a gage taste, but one I could have seen myself doing without. So I know different things taste different and I don't expect everything to taste like chicken so to speak and I was thinking maybe that is just something to get used to.
Today my wife asked me to help her make some bread sticks and when reading the ingredients she called for 2 eggs, so I said lets use the duck egg. So I go to open the egg and I noticed real quick it was brittle and cracked into small 1/4" fragments, which I do not want in the mix, so I started pealing off the 1/4 inch pieces of shell from the air sac. It became clear to me very quickly that if these were like chicken eggs that they had been stored for at least a couple of weeks, which gave me a good opurtunity to show my wife why eggs that are stored peal easier when hard boiled due to the evaporation of moisture which gives more room for expansion and all of that. So basically instead of cracking the shell like normal I revealed a large portion of the sack and broke it. Then I smelled the smell only a little stronger and it smells like mud, light mud smell but still mud, which I have never seen in a bread stick recipe- we will see how they turn out.
I have cleaned a goose before with that same smell and an older fellow told me it is because they basically eat in the mud so I am thinking either that is the same case with the eggs or maybe while the eggs were laying in the mud they got the taste? Or maybe that is just duck egg taste?
I don't know but what I am wondering is if you get the same taste in an egg from a duck that doesn't have access to mud like a duck around a pond would. And as far as my description of cracking the egg and the way it fragmented and all of that, is that the normal duck egg experience, because if so I think I will stick to chickens please. But I do think it is cool that the lady has so many eggs this time of the year because I have 7 chickens (hens) and I am lucky to get 1 egg a day.
In the spring, known as mud season in Maine, I've pulled eggs off the top of mud and washed them. If they've been there for just a few hours, no mud flavor or smell, but some light staining. After a few hours, definite smell/taste. My eggs, laid clean, stored correctly, even a couple weeks old just taste like egg. Farm fresh gives it a stronger egg flavor, but that's it. Normally I don't even wash my eggs, the bloom keeps them fresher longer.
