The first bird might actually be splash laced (looking at that large white spot on one of her feathers). The second one looks like a blue laced red, but might be splash too i can't tell. The last two definitely look splash to me.
Splash is an incredibly variable color, it can be almost completely white with only a few specks of blue or it can be a light blue with darker flecks of blue, and anything between those two extremes.
Can we see the "gold laced" birds? Since blue is one copy of a dilution gene and splash is two copies, when you breed two blue birds together you get chicks in all three colors. I'm curious if the gold laced are actually black laced red or maybe dark blue. Also wondering how old these chicks were when you got them? Blue is super variable, sometimes it's a very pale grey and sometimes it's so dark it looks black and chick down can be tricky. It took over a month to figure out if my blue laced red wyandotte chick was black or dark blue.
