Confirming the gender of my chickens

[Mini-Daisy]

Hello,
I'm new to raising chickens and even though I'm was quite sure my chickens are all hens when they were some days old,
it would be great if someone could confirm that for me


They hatched on the 3rd of May so they are at the moment 2 month old. The 2 darker coloured chickens developed some greenish tail feathers lately which I thought could mean they are roosters

Thank you very much in advance!

With that amount of comb,wattle development and redness, you have two cockerels and one pullet, in my opinion

I agree

The green sheen on the black feathers does not indicate gender. Its a bird trait, not a male/female trait.
That said, at 8 weeks, two of your birds have a lot of comb and wattle. I agree with the above assessment. You have one pullet and two cockerels.
