A molt can make a huge difference in appearance, that's for sure--especially while it's in progress
The toe spacing is really no big deal. If the bird has five toes, that is all a judge cares about. For most breeders that is not a huge consideration--other traits are more important.
One question--could the off colour in the hackles be sunburn rather than silver or gold? (of course, the blue would often turn brassy, too) If sunburn is the case, after his molt is complete the hackles will be clear. Mated to a hen with very dark skin you will probably have better comb colour in at least some of the offspring.
