I have two young ladies born right here at my place.
Their father is a green egged, hatchery EE. Their mother is a cream colored egg laying Barred Rock.
Both of these gals are pretty much solid black hens, though one has a bit of a green tint to her black feathers, and the other has a silvery tint to her black feathers.
They both are pretty good layers of nice, cream colored eggs. At one year old, their eggs are around 2 ounces each ("large" by USDA standards).
They lay probably around 4 eggs a week. I'm not sure because they live in a group of 13 hens, many of whom are cream colored egg layers.
BTW, these two girls a half sister who shares the same father, but whose mother is a buff orpington -- making this young lady half EE/half buff oprington. This little girl is mostly gold, but with beautiful darker tan highlights. She lays a medium sized egg (about 1 7/8 oz), which is a green egg that sometimes has very small brown spots on them. She lays about 3 times a week.
