One of our unregistered pygmy girls has toggles - her brother didn't. Neither parents had toggles, but dad has a big beard, but none of the kids inherited a beard.
As to size, although unregistered, most of our kids are small, but not as small as my registered nannies were. Father is what I would call oversized, but we do use him on the smaller dairy goats too, and these kids tend to stay smaller than their mum. Our other pygmy billy, Elliot, is a lot smaller, and his last owner said he was from registered parents, but she was adamant he was big for a pygmy, but as I pointed out, the males will be bigger.
Unless you really want a small pygmy, then I would not worry too much about the size.
