Well I hate to put damper on your Wellies but I've heard about folks very disappointing with Ideal's Wellies because their egg color were not correct, some were too light, just ordinary brown eggs. So I stayed away from hatcheries (except for Estes Hatchery which they bought out all of Harry Shaw's Welsummers when he passed away) and stuck with real Welsummer breeders.
For me, I would stick with Wellies tht would pass on the wonderful terra cotta colored eggs. Contact Mothergoose or SpeckledHen for possible hatching eggs.
All my girls are from Mothergoose stock, Gordie's and Calicowoods lines.
Good luck!
