My welsummers came from Meyers, the roo I kept is pictured as my avatar at about five months, his tail feathers are much longer now. He's the one I kept because his colors were the nicest, AND he was slightly smaller than the RIR cockerel and they are supposed to be smaller. Two other wellie cockerels were as big as the RIR, and colors were dull. Only one out of three pullets had correct color on the neck. I don't think Meyers has breeder quality welsummers, but I did get two that look like they are supposed to.
Her eggs are always spotted, various shades of brown but definitely darker than other brown egg layers. She has been laying very good this subzero winter.
I like them because of they are pretty birds and the eggs are cool, but any of the other duel purpose birds would make better meat IMO.
