After my late wife's dad got Leukemia she (Marie) spent part of her  childhood growing up on her uncle's farm.  She used to always go on about how good duck eggs are.  I am 65 and never got the opportunity to try them.  It was high on my bucket list. On Christmas my niece Julie, who has ducks, gave me a basket of them.  They are considerably bigger than chicken eggs.  I expected them to be good but stronger tasting than chicken eggs.  I half expected a slight fishy taste to them.  I was completely wrong.  They taste much like chicken eggs but milder. They are excellent.  If you get the chance, try them.

because ducks have a better dieat than most chickens the yolks are yellower and richer.
Ducks don't eat fish, pretty much vegetarians.

Only way to beat a duck egg is to go for a goose egg !
Those things are huge - one egg omelettes ,

My gf watched a few YouTube videos a few weeks back. She has been on a kick about emus.  She wants a few of those, to raise.

On aside note, we are waiting for Turkey eggs, we have been told those are good.

@Ca, our ducks have the same diet as our chickens,  and you can taste the difference in the eggs.,  they eat lots of bugs, when wee have no snow,  theh eat a ton of slugs.

Not sure what emus you're talking about , Australia has no natural predators for a bird that size , think they would get smashed by North American predators.
And another thing is I got no idea how legal it is to obtain a emu, they're protected here with the exception of cultural hunting. And sadly I think you could say a few would have been lost in the current wildfires.

  My niece called me yesterday and said she had more duck eggs for me. When I arrived at her house she said they are getting four dozen per week... more than they can possibly use. So I can have all of the free fresh duck eggs I want. This is a major score.
    Somehow I didn't notice with the last batch I had but the yolks of duck eggs taste richer than those of chicken eggs.
