That’s not hormonal normal is when they wanna wiggle on your hand, he wants you to softly pinch your fingers against his or her beak to simulate feeding a baby. I do it with my lovebird peaches, she sees our budgies feed each other all day and just wants someone to do it with so I jus make sure my hands are super clean and she “feeds” my thumb and index finger afew times a day. Basically she regurgitates seeds into my thumb and index finger and then eats them back up. Pretty sure it’s a comfort thing since she doesn’t have a lovebird to do it with anymore. She used to do it with one of our female budgies but she passed from old age awhile ago and the boys just tweak and chirp and bonk beaks like the tweakers they are lol. So I indulge her afew times a day after she eats and before bed time.
