i raise royal palm turkey ( white ones ). used to do the bronze as well.
if they pick too much.. salt their water. used to you could buy a blue salt powder called pick-not sold mainly for chicken.. but works with most foul.
you can also get some comb dressing if his head is bleeding bad.
the salted water usually stops picking and canibilization pretty fast.
if i have a turket that won't for whatever reason get along with the others.. or is bullied and won't recover.. i put em in with the chickens. they don't mind.
i don't clip beaks..e tc. I have put wire nuts on some large leghorn and RIR monster roosters before though.. been spured bad enough to go to an outpatient clinic to get an inch of spur removed that broke off deep one time. that and a tetanus shot and a week long course of antibiotics :)
