In my experience duck eggs taste a bit eggier than chicken eggs and taste noticeably different when compared to storebought eggs. They have an almost overwhelming taste to those used to storebought chicken eggs. They are good, but they are rich and stronge tasting a good way. Start with scrambled eggs and not overmedium or anything runny. This will give you an idea of the taste without being overwhelmed by it.
Just my opinion. I also believe that goats milk does not taste a bit like cows milk, but like goats milk.
If you like rich, gooey brownies, then substitute duck eggs for chicken eggs. The difference with shock you.
I am finally getting fertile duck eggs. They are pekin/buff crosses, but I don't really care. I have to wait about a week before I can set them and I will be hatching some for the Easter hatch. I brought over my pekin drake from mom's to go in the pen with Daisy and Daisy, a buff and a pekin. I can't remember which one i named Daisy, so they are both daisy.
