my chicks started picking in a really short period of time. in my case, they were getting crowded & bored. i had to separate three that were pecked badly. i put blu-kote on their wounds. it worked really great. it served as a topical antibiotic & camoflaged the wound so further picking wouldn't occur. just wear gloves or something because it stains big time. those three girls wore that blu-kote for a very long time before it wore off.
