My experience is that gold (red) leaks the most with recessive white and males will show it more than the females. I would try getting a new cock bird from a different line.
Looks like a wheaten cockerel and two pullets. They are of the wheaten variety. They hatch out with pink or skin colored legs and feet and they get darker as the bird matures.
If a bird is clean faced, it does not have a copy of the beard and muff gene. A good breeder will eventually weed out any birds that are producing clean faced offspring.
I would also say that your new girl may be a cockerel. Generally cockerels develop red on the wings, not pullets.
I would also day the bird is an easter egger, not an ameraucana.
