Also try contacting local hobby farms and breeders. I recommend Metzer Farms, the farm is in California, but they ship the eggs quickly and safely. I purchased Chocolate Runner and Cayuga hatching eggs from them and all 6 eggs hatched. Metzer also has Welsh Harlequins.
There is a lady in the western part of NC that sells welsh harlequins, she should have some available in March; Blue House Farms, She is on the net....
