Whoa, yeah, try to get the problem fixed!
The Marans folks would flip over before they're in the grave if they thought someone thought a Welsummer was a Marans. I actually dont know that much about Welsummers, but I do believe the Marans originated in France, there is always an "s" at the end, there is a very passionate following (yeah, I'm getting there) for this historic breed. Welsummers are cool too, but an entirely different breed that puts out a deep terra cotta colored eggs. (Marans lay a darker brown egg).......Good luck, its actually a fun subject to explore!
