12 week old Rhode Island Red Pullet or Cockerel?

[About15chickens]

Please help with identifying these RIRs. They are 12 weeks old and came from TSC.
I am giving the 3 of them to a friend this week and want to make sure she knows what she's getting. I thought all 3 were pullets. They did not have white spots on their shoulders as babies and have seemed to be pullets, but now I am questioning #1. Getting redder than the other 2 and is a little bigger. Couldn't get a picture of #3, but she looks like #2 and is small. Compared to our for sure rooster Sapphire Gem, who is huge and has a giant comb, all of these appear to be girls but I wanted to ask.

I believe they are pullets. The first bird is just maturing earlier.

Looks like a pullet to me.

Look just like my rhode islands. And i was told they are pullets too. The tail feathers may look a bit uneven but thats not uncommon with those. I attached pics of mine at around 11 weeks.

I have several RIRs and they run from dark, glossy red to a light brick color. I ordered 12 sexed pullets and got 8. The other 4 were roosters, yay. The roosters have a more pronounced comb and definitively pointed neck and saddle feathers. And they are delicious.
