Ooooh they're CUTE I want to say Sweedish. The top one looks like a crested Blue Sweedish duckling. The first pic of the other two made me want to say Cayuga, but it almost looked like they had some cream/yellow on their chest which makes me think black Sweedish.
Absolutely LOVE that little tufted gray one... so so sweet!
I got them last wednesday and I've been on these boards reading ever since. I thought up until yesterday the black ones were cayugas but now I'm not so sure. The first one I had no idea on. He's the most anti-social of the group.
The two black ones could still be Cayugas. My Cayugas all had pale yellow or grayish areas on their chests just like that when they were ducklings. The only way to know for sure is when they all get their adult feathers in, though.
