Help Id this breed

[gwells1980]

I was given this chicken a couple of months ago but the owner didn't know what it was. I assumed it was a Sapphire Gem as those seem to be everywhere now. However after comparing it to photos I have seen online I am not so sure. Sapphire Gems I have seen had yellow legs and feet and pale skin with red faces. Mine has solid black legs and feet, black skin, and enormous red waddles and comb on a black face. She lays extra large or jumbo brown eggs everyday without missing. Any help would be appreciated.
With all the blue or lavender breeds running around, I am at a loss.

I think it is a Sappire Gem. They often have black legs, and they lay tons of large brown eggs.

I agree that that's the most likely breed/cross she is

Thank you both, JedJackson and Rhodebar Lover. I guess where there is no standard because they aren't a breed, they can have variations.
