3 chicks: Hen or roo ?

[1DLuna]

I purchased these 3 babies from a local feed store and they are suppose to be 2 Easter Eggers and 1 red sex link. They did say it was a guarantee they would be all hens. However, I’m starting to get nervous lol #1 & #2 are becoming very aggressive towards me when I open the coop door are they giving roo vibes? #2 seems to be growing small wattles. #1 & #2 are the tallest. I’m not sure how old they could be… 3 weeks possibly 4?
They told me they came from a hatchery. First time raising chicks.

Are you hand feeding? Some say it isn't an issue, but my first four that I hand raised were brats because I didn't set boundaries when they were little. You can still love on them and spend time just hanging out, I just wouldn't recommend hand feeding in particular. Mine started pecking at my hands when I didn't come bearing treats, not hard or trying to do damage, but it would get a bit rough as they got older.

I don't see any thing that indicates cockerels at the moment. It could take at least a couple more weeks to be sure they're pullets though.
