There's no reason to think they will lack in laying genetics. I'm sure their parents are picked for egg laying abilities. They will NOT be sex linked colors however. You need a brown drake on a black hen to get the brown girls. So, whatever cuties you have, you will have to wait to know their sexes. Also, they will probably be more varied then their parents in physical type, as the genes sort out through another generation. I would consider them for egg layers. I suppose that, if some non heavy laying breeds were used in the original mix, then the f2 offspring may not lay as well as the parents. Since we don't know much about the original stock, it's hard to say.
Those r very pretty ducks. I saw they are available from Metzers the hatchery claims to have developed them as a dual purpose bird. I thought about ordering some but I am going to wait to see if I have any female Swedish first. Your ducks look very happy
Btw love your patio
If it's first-generation Golden 300 you''ll be able to tell at any age by the colors. Drakes are shades of black while the hens are shades of brown.
"The Golden 300 Hybrid can be sexed at any age by its color as the males are shades of black and the females are shades of brown. Unfortunately, they do not retain this characteristic in future generations. So if you mate a Golden 300 Hybrid with another Golden 300 Hybrid, their progeny will hatch in blacks, yellows and browns with no relationship between sex and color."

Here is my Golden 300....who is the sweetest thing.....I ordered female ducklings and at 8 weeks old now she/he is the only one NOT quacking, very quiet, so I am inclined to believe it is a boy....but the coloring says female to me?! Time will tell I suppose but I’d have to think I would have heard a quack by now!
