Wow, that's a really nice Welsummer egg!
Well, it was rainy out, so I couldn't get the best photos, but here's an Olive Egger pullet of mine. She's rumpless, and half Gold Duckwing Araucana, half Wheaten Marans.
Another rumpless Olive Egger here, half Blue Cuckoo Araucana and half Black Copper Marans.
And yet another, this guy got the other 50/50 of being tailed. He's half Blue Cuckoo Araucana, half Black Copper Marans as well, but has a single comb. He's huge though! Pardon the ground, it is wet pine shavings. Looks like poo, but it's not.
Sadly though all my Olive Egger chicks so far are Araucana crosses, NONE have tufts. My only tufted cross is an Easter Egger cockerel. Most of the Olive Eggers have well feathered shanks, but the first pullet has clean shanks. My Wheatens are lightly feather-shanked, so the most I got out of them was a couple feather stubs on a cockerel. Also, all my Olive Eggers but two are boys. There's the pictured pullet and another blue, tailed pullet with a lot of gold-dusted mossiness.
It will be a while before I get to see their egg color.
