I had actually come to this thread earlier this year when I got my two Meyer's Olive Eggers. I decided I'd post some stuff once they got older so here they are~
Below I have a mix of chicks. 2 Olive eggers, one Blue Andalusian, and a blue laced red wyandotte. The BLRW is the brown one, and the BA is the pretty blue one with the dark beak. The bit of the olive eggers are seen by their butts and butts alone. I got a black one with a bit of yellow fluff, and a grey one (far left) with yellow on it's belly. They had a bit of fluff on their legs but as they grew those disappeared.
Again, below, you can see the black one and the grey one to the far right (middle grey is the BA). they had greyish, slate colored legs.
Here they are when they're a bit older. The black turned out all black with a muff, and the blue has no muff and had a bit of barring on the shoulders. They are my most unphotogenic chickens I swear.
The olive egg here came from one of the two above as I only have two. I have two easter eggers that lay a very pale mint green (one is pictured for comparison). I was surprised I got such a nice color form a hatchery but here I am, pleased as all be over this dark green egg!
I will say that all of the olive eggers that were shipped to the place where I got my two chicks were all either black with a bit of yellow, or grey with a bit of yellow. All of them had a bit of feathers on their legs and they were all slate colored.
