That is quite strange my does are the same colors as yours Buttercup is my avatar. Blossom is tri-colored, and Bubbles is tan with a white band around her middle. Luckily mine did great with their kids. They don't give much milk but it is good, I get about a cup from each.
The two wethers that I'm Buying are recorded grade, so their names are:
Buster (don't have a reason!)
Creeper (Stalks you when it's dark... jk. he's just very friendly!)
