I think they told me Black Copper Marans is all they breed. Some of them look as if they don't have feathered feet at all though. They will be 4 weeks on Thursday.
Here are 2 of them without feathered feet when they were about a week old, they all hatched Thanksgiving except one that I had to save out of its shell.
