Yeah, I thought the chicks of WJG chicks would be a little grayish, but I saw Hoover hatchery had a picture posted of one that was pretty white. I’m really interested what it turns out to be, I can’t think of anything else that would be white with the slate colored legs.
If I had to make a guess as to a breed maybe White Jersey Giant? But I don’t personally know the breed and technically it’s not on the possibility list, although Black Jersey is on there twice.
