I got my chickens at a small, local hatchery. I called them when I realized my bird wasn't a Cochin and asked which other feather footed breeds they had and croad langshan was one. They assured me that they don't let their breeds mix, except of course the chicks that hatch. And it's entirely possible that I was given a langshan instead of a Cochin.
Thank you for your photos.
Definitely not cochin! lol
I don't have langshans, and don't know the breed, but from pics, that does look like a possibility. I have a couple Marans, and see a little resemblance, any possibility of Marans from the hatchery?
