Fowlsessed- Gold duckwing and wheaten can be kept together and will give you some wheaten, silver DW, and GDW offspring. Blue reds and wheatens would give you some of each also.
Troyer- those birds look good. Don't worry about leg color, use that as a tie breaker Between otherwise equal birds maybe. You can fix leg color later. You may want to consider this way of judging birds to keep and birds to cull. In order- Vigor, Temperament, Size, True Breed Type, and lastly color. Yes, yellow legs mated to yellow legs will give you all yellow, sure, but yellow with white or slate should get you mostly non yellows. If you get an awesome bird with a color fault, just breed it to a mate without the color fault. Ideally all your breeders would be perfect, but, it's not an ideal world. It looks like you ate making really nice progress this year.
