buy rooster booster peck no more and put it on the chick it treats the wound with tea tree oil, covers the appearence of blood and it stops the others from pecking her. i used this on my chicks when my pullet was pecking and bullying them. it works like a charm! my bird pecked once that was all it took because i put it on my chicks back it was soooo nasty to her she stopped pecking them completely! i stopped using it she still won't peck them anymore! it won't hurt the chicks at all. its about 6 dollars at the feed store. i can honnestly say it worked like a charm for me! yes it smells strong but that's the point. it stops that pecking fast! its a thick purpleish lotion. it works amazingly! also treats the wounds and covers blood. great stuff! i keep it on hand incase someone starts pecking where they shouldnt.
