Figure out who the bully feather-picker is, and give his/her beak a trim. Use the large toenail clippers, and nip off only the TIP end of the top beak only. Then you'll see a little curved gap there - this gap allows the feather being picked to slip through! Clipping a tiny bit of the beak is painless, and it grows back. Don't go too far, or it will bleed.
Of course, if anybody's bleeding, you'll have to separate them - when chickens 'see red' they have to pick at it - - - - Hope this helps all of your picking problems - - - - -
