I ordered the same special and have one who looks yours here. I'm not sure if its a brown leghorn or a welsummer. I'm waiting on the earlobes to appear before I give up hope that its a Welsummer.
My latest theories on mine are:
1 brown leghorn or welsummer
1 white crested blue polish
1 white crested black polish
3 white clochins
1 blue or splash cochin (its a lighter blue than the polish)
6 white leghorns or white rocks, waiting on earlobes on those as well
3 silver spangled hamburgs
2 silver lakenvelders
2 golden campines
2 black sumatras
1 black that I'm not sure about. If I didn't have the two that I am sure are sumatras I would think it was a sumatra, but it looks different than the other two.
1 white rock/leghorn, 1 white sultan and one white crested black polish didn't survive.
