Quote: I disagree. Polydactyly, like blue, has varying degrees of expression. Now if the bird has the extreme allele where virtually an entire extra foot is present, I would say not to use for breeding, but not with an extra toe. However, like everything, it really depends on the rest of your flock, and the bird's other traits. If you have plenty of other equally good options, sure, pass on the bird, but if that bird is otherwise the better choice, use it.
