One of my favorite chickens in the world, Barry, wanted to be a mama. She couldn't hatch her own eggs so we bought her a few chicks to mother. She was a ferocious mama but we lost her last year. Two of her brood are to tell apart, hence The Twins.
The Twins are now old enough to lay eggs. We were told the Twins were Novogens as chicks but I think she lays an dark green egg not brown. This makes me thing they are Whitghting True Green.
