Here is a good primer on Lakenvelders and Vorwerks.

Now I see, the Lakenvelder is the silver Lakenvelder (black neck, tail and white body) and the Vorwerk (like @dheltzel said) is the Golden Lakenvelder and is made from a mix between a Lakenvelder and a Buff Orpington.
We're loving getting the odd double yolker! Another bonus since cutting the reliance on the supermarket for our eggs.
