Well if u quarantine her in a small space from the others u can easily catch her to socialize with her and maybe if u get her to calm down she won't peck at the other but is she a buff Orpington also as buff orpingtons are a calm gentle breed and if she is a diiferent bred she may have a different type of gentleness if u want to call it that and chickens Will actually peck birds that are more docile like the Silkie and Kept with maybe a Rhode Island Red they have a different temperament so they are gong to want to peck and hurt them until they kill of hurt them

she has pecked me a lot too. I think it is just normal chicken behavior of liking shiny objects and sometimes she even acts scared of me so i don't know but she has pecked my gums last week and then yesterday my eye. And she pecked my albow hard once and made a mark
