Khaki Campbell duck sexing?

I need help with gender…

How old are they? It looks like the closest is a girl and the rest might be boys.

With the darker tails, dark heads, and larger size I'd guess the two on the ends are male. Going off the same head coloring and size I'd guess the one in the middle, closest to the pool, is also male. The closest to you in the middle looks like a girl with her lighter, uniform feathers and being that much smaller.
