Love the article! Exactly what I was looking for. I too had a hard time seeing all the pictures. We found Welbars a few years back at TSC. They are some of our best chickens. Haven't found them since.
Wow, what a well researched article, thank you for this in depth information.
Another autosexing breed that is now available in the US is the Bielefelder, known as the German uber chicken. I've read this is a very docile dual purpose breed, large, early to lay, and a surprisingly productive layer considering their very large egg size. Hens are very prone to being bullied by the more assertive breeds, so not for all combined flocks.
