I've seen 3 chicks that seemed aggressive.
First one was real aggression, he'd rip other chicks apart (literally).
Second one had only ever eaten food out of hands so whenever he saw hands he'd peak them wondering where the food was for a while.
And the third was a pullet (around 7 weeks), not sure why but she'd leap and kick my hands and peak very hard at me every time I went to clean or feed them. I was determined not to give her any sort of reaction though and she gave up after a couple of tries. Since then she's grown up into a lovely hen and we haven't had any issues with her.
I think for your situation most importantly don't give a reaction, if she starts trying to rip you apart while your cleaning, act like she's not even there and continue what your doing (if it's hurting put on some gloves), you dont want her to know she can hurt you, and you want her to give up trying to regardless of why she's doing it.
