Cockerell or pullet? Sexing 10 week old light Sussex chicks. Gender guess

[SnowyJball]

I've got 3 light Sussex 10-week old babies, who I really want to know the gender of. It's my first time raising chickens from chicks, and I've had these babies since day one. I really need help identifying their gender. any ideas?

If any MORE PICS are needed, PLS COMMENT

basic info:

1# Cloud - Is slightly smaller in size than the other two (since the days when I got him/her) Cloud has a longer, pointer, and more developed tail than the other siblings

2# Wind - Is in between the size of cloud and rain (middle size) Very good at flying, and I think has a slightly (barely noticeable) larger comb.

3# Rain - Is a lot chubbier and bigger than the others, got very long and thickish legs, has the widest body structure, and is the tallest and heaviest.

Similarities:
- They all got a bit of development in their waddles and combs. Not too much of a difference
- All fully feathered (as shown in pics)
- born around the same day (not sure if they are from the same mum, as they only have an adopted mother)

You're going to need lots of opinions on these because they all have very similar development and coloring in the combs and wattles. They all look kind of in between. But my best guess is that they are all females.

All look the same, haha.

#1 is the only one I’m not sure of. The other two look like hens.
The comb on Cloud looks a little darker. And the tail feathers are definitely more pronounced than the other two.
But I can’t see the saddle feathers very well so it may still be a toss up.
