Every breed needs it's own message thread, right? Even if it is still rare.
Welbars were created in the UK in the early 40's as part of the autosexing chicken "craze". They lend themselves very well to that, being one of the easier paths to clearly sexable chicks. Originally intended as a utility breed like Rhodebars and Legbars, they fell out of favor even in the UK, but apparently a small number of breeders have been keeping them from going extinct.
There are a few pages devoted to Welbars. The best I have found in hours of research is this one: http://www.harislau.info/welbars
I have spent the last 3 years recreating this breed from the original genetic "recipe". Welbars are often used as an example of how an autosexing breed is created, but they have never been imported to the US (that I have been able to find).
Here are some pictures from my flock:
A major concern with any chicken is the eggs they lay. This is a comparison of Welbars, Welsummers and Copper Marans, all gathered directly from my flocks.
Of these 3 breeds, my Welbars are clearly laying the most eggs per hen.
