Hi... and Yep, it looks like your's are going through molt which makes it a bit difficult to judge the colors. Looks like your girls are carrying chocolate though. Any of your colors that carry chocolate will "fade" over time until molt which makes the colors look muddy as the year goes on until molt. #1 female is a nice lilac, #3 female looks to be black pied but carrying chocolate ....or maybe a very very dark chocolate since she has some faded chocolate feathers. Drake is probably blue though he has a lot of white & the blue isn't laced so could be self blue or silver. The juvenile drake is blue carrying chocolate it looks like. Maybe a few more pictures closer up??
