@aart is so right here! Peckpeckpeck, fast as possible, until the pullet moves away. Wear jeans, socks, and boots or shoes, always best out there anyway. One of our 2021 pullets has been like this, and by being very consistant, and firm, she seems to be over it. Finally. Now she follows me around, and it's cute, and at a respectful distance. She's pushy!
This spring sometime she tried one more time, a nice bite on my jeans. Would have been a wound if I was wearing shorts! She was not pleased by my response!
I don't hand feed, rather call the birds and toss treats on the ground.
