My hen turns aggressive overnight

[Coffgirl]

She's 5 months old and was always sweet and very attached to me.
but yesterday she started to be really aggressive out of the blue.
she makes chatter noise, pecks my hand and tries to aim for my eyes.
I really don't understand why this happened because she always was sweet even the day before she went aggressive.

I'd like to know if anything can cause this to happen and will she will be back to normal?
please help this really breaks my heart.

Are you sure that it's not a boy? Or maybe it want's to go broody?

Possibly broodiness! Can you post a pic of her? She might be a roo. At 5 months old, a roo’s teen hormones take over and they turn aggressive. It’s heartbreaking to many. Good luck!

This is her picture, this one when she was calmed and friendly

also she's not a boy because she lays eggs.

She'a a bit young to go broody. Usually pullets get friendlier once they start laying. How long has she been laying? Maybe try not approaching her for awhile.

She started laying at her 8 weeks old

Are you picking her up?
Chicks are often tolerant of human handling but as they get older some really don't like being handled, expecially if you take their feet off the floor.
I would suggest you re-establish friendly relations while she's standing; gently touching her beak while you hand feed is one method. pretending to pick mites from her crown and wattles is another.

she mostly jumped on my lap by herself most of time but now I can't even hold her because she keeps pecking my hand so I can't even pet her back.

I picked her up a lot back then and massaged her because she seemed really calmed and she tried so hard to stick on me so I can't believe it just changes overnight.

The chatter sound sounds like a broody to me.
look around in her house for a hidden nest.
My broodies do that chatter thing when birds come near their nest. It means back the f off lol. Sometimes they do it when they're getting ready to lay too.
