I'm happy to learn the explanation of the light legs. My BW Amer's sister had a few very light blue feathers and very pale blue legs but was the one I lost before POL. My surviving BW (my avatar) is such a love - but she never had the few faint blue feathers mixed in her body nor the pale blue legs of her deceased sister. I've had a Blue Amer and a BW Amer and we adore the BW - never had such an extremely kind bird. In the 2 years we've had her we never once caught her retaliating against the Silkies who chest-bump her and she is very tolerant of them never once nipping back at them. I re-homed Marans and Leghorns for being mean to the Silkies but the BW Amer continues being kind and submissive to the bantams.The leg color is the result of the wheaten gene . Yes buff has it also . The lightening of the plumage also lightens the leg color . When doing wheaten or buff crosses you will get black tailed buff looking birds . These always seem to have darker legs . Once you breed back the correct colors the leg color is light .
Her eggs are very pale blue (a BW trait maybe?) and not the better shade of blue I see in photos or on the egg chart but they weigh 2.3 oz consistently which are a better size than the 2.25 we were getting from a White Leghorn. In 2 years she has never gone broody - guess she leaves that job to the Silkies! Not one breed can fulfill 100% of expectations - the Amer is a jittery jumpy kooky spooky noisy wary personality but once we got past those predator-savvy characteristics we found the Amer a very personable sort that will allow petting, holding, and is quite the conversationalist! Easily trainable too when setting up fence barriers to keep the flock out of the raised bed garden. Amers are excellent flyers but ours respects the short 2-ft rabbit fence boundary around the garden. And we found the BW very kind and tolerant to flockmates preferring to avoid conflicts or combats and is very effective as the guardian sentinel of the flock. Often we find our BW poking her head out of her nestbox at night to check on our activity on the patio if we're coming home late. The Silkies won't move a muscle but she has to check things out.
