In German those dogs are called “Deutsche Schäferhunde”, which literally translates to “German shepherd dogs”. My guess is, that this was simplified to just “german shepherds” over time.
In dog breeding/training circles, people still say “German Shepherd Dog” fairly often, even though you can just omit the “Dog” part in casual conversation. The initialism “GSD” is extremely common, too.
My understanding is this kind of thing is more common in birds that recently started laying. Combine that with the fact that birds tend to be kept with other birds of similar age and it’s not uncommon for a package of eggs to have either no double yolks, or multiple instances of double yolks. I’ve never seen a dozen eggs with just one double-yolk.
That makes sense, my two laying hens are the same age, while my other hen and my roo are younger. And I’ve only been getting eggs from them for a month or two.
Strange. A weird “fact” I heard in my childhood was that the yolk contained more protein (also called eggwhite in German) than the egg white. Meh, too tired to research it.
