Super busy yesterday! I tend to have those days also when you need to do a bit of work out side and you come in and it's time to eat dinner! It happens to the best of us. In doing a little catching up...I saw the conversation about duck eggs.
I eat duck eggs pretty regularly. Other than size...the biggest differences between duck and chicken eggs are that duck eggs have a higher amount of fat in general, which is what really makes them much richer. The other thing is they have a much better Omega 3 fatty acid profile. But I think (and this is just my opinion) is that you typically don't have commercially raised ducks that produce commercially harvested duck eggs. So the ducks have a better diet than the chicken hens that never see the outside of a cage and are only eating feed. If I had to bet, I would say that a pasture raised chicken hen that has a large plot of land available to them for foraging and finding all sorts of bugs, worms, grubs, stone, soil, and some grain will lay an egg that has a similar Omega 3 profile as a egg laid by a duck.
Anyway...I get duck eggs from my niece who has a few ducks. Nothing big. Her ducks pretty much eat what they can find in her yard. Bugs, grubs, worms, frogs, lizards, mice, whatever is outside. She will supplement with meal worms and other organic things for them.
My sister in law at any given time has about 12 ducks. She has a big pen that her ducks mostly stay in. They will get out during the day from time to time, and really just eat bugs and such and then go back to the pen when they are satisfied. She has a big coop that she built and puts them up every night. They pretty much just took to going in the coop after a couple times of training. But now when a new duck is introduced, they others just get it in line. She has had a couple mishaps with coyotes, but all in all...she raises some pretty healthy ducks.
I personally wish I was able to raise a few myself...man I love those duck eggs!
