Hi Y'all.. I have five Buff Orpingtons... and I just have a question about leg color. Four of the orpingtons have whiteish legs and one has yellow legs... about the same color as my Welsummers legs! Just curious if it's possible that it is a different breed that got mixed in? It looks like the other orpingtons, except for those legs... and it seems a little lighter built, but I may have been imagining that. I'm not an expert at all on chicken breed shapes and identification.
You probably have a Buff Plymouth Rock then. They have yellow legs and are often mislabeled or put in the wrong box going to the feed store.
