First duckling hatch of 2025!

[My15Ducks]

I would love any help figuring out what color these ducklings are!
Here’s some info on the parents: one mom is a black runner, and the other is a black Cayuga mix. Dad, Banana, is a mystery based on the color of the ducklings, I think he has 2 blue alleles. If he has 1 or 2 chocolate alleles, any duckling with a chocolate allele will be a girl! But I’m not sure if I can tell which ones might have chocolate! I read that lavenders and blues are almost impossible to tell apart as ducklings.

It looks like I have 3-4 different colors in this batch. I’ll post photos of each color separately.

Color #1.
I have 1 duckling of this color. It has the mallard pattern, but other than that I don’t know! It can only have 1 blue allele. Could it have chocolate?

Color #2. “Dark blue”. I have several of this color. My top guesses: Blue dusky, blue, or Lavender?

Color #3: I have 2 of these. They have mallard face stripes but no mallard back markings. I have another one that appears to be the same color but has the full mallard pattern.
My best guess: Blue mallard?

Color #4. I have a lot of this color. I really don’t know what color they are except they are the lightest ones. Could they have both blue and chocolate dilution?
