We have one lone guinea (a male) who wandered down from the neighbors and decided he'd rather live with us. We've had him for about 4 months happily coliving with all of our other poultry (15 chickens, a turkey hen and a tom turkey). About 3 weeks ago we got 6 1 week old keets and moved them outside to the coop (still caged) about a week ago. Two days after ago our male adult guinea started relentlessly attacking our tom. He would hang on to the toms side as the tom tried to run away and pull feathers out. The tom now has no tail feathers and is missing some breast feathers as well. We somehow managed to catch the guinea and throw him into solitary confinement to give the tom a break and a chance to heal. The guinea wasn't bothering any of the other birds or our rooster, only the tom. Is this normal behavior? Is he somehow trying to protect the new keets? We hate to get rid of him but there's no way we can keep him if he's going to always attack the turkey. If it's just a temporary thing we can keep him confined but I hate to do that if it's a problem that won't go away. Anyone have any clue what caused this sudden hatred of the tom?
