Today I decided that we have accumulated enough eggs so we can prepare something for breakfast with our overnight visitors (software development crew, usually remote work but sometimes we like to get together).
I was a little worried because I have read many descriptions ranging from "like chicken eggs, only more so" to "the white is leathery unless prepared in some special different ways". Our practical experience was definitely the first, ie. they are simply eggs, no special treatment needed, but very good ones. Good taste, good coloring. We did a simple "sunny side up" dish just to establish a basic starting point.
This is still experimental small scale production - 5 ducks old enough to lay but usually just a single egg per day and yesterday there was unexpectedly one in the afternoon as well - must have been from the same duck that already laid an egg in the morning because the shell was rubber

The content was fine though.
