Ahh, I love all the colors I've seen.
We have owned Royal Purple, White, Pearl, and Lavender. Royal Purple are beautiful and definitely one of my favorites. White are also very pretty and another favorite. I like pearl, but they are very common so I tend to dislike them a little more than the others. I do enjoy my solid pearl hens though. I would have to say, out of the colors we've owned, Lavender is my favorite. Give it to me pied or not pied, it's always beautiful.
I would like to add a few more colors though. The Buff Dundotte I've been seeing are gorgeous! I also want some Chocolates and Coral Blues. Someday, lol.
And if I'm not mistaken pretty much any color can have pieing correct?(And I assume pied is rather dominant? We have 1 pied cock and have gotten 20+ pied keets)
