Ive tried all the methods suggested when i originally posted several months back, but lately she is getting worse, ive tried everything and im about to add 2 more chickens to the yard and i don't want this to be a problem when i try to add the new hen and the temporary roo to the yard. what can i do to get this hen to stop. im hopeing putting a roo in the yard for while might help put her in place. everyone near me with chickens has never see a chicken attack like mine attacks me
