I have seen 2 pigs absolutely attack chickens. We had pigs in a pen with an open top in a barn. Chickens also went into part of the barn to eat and roost. The pigs were fed slop (food scraps) in a trough. The chickens would hop down in the pen the pigs were in and pick at the pigs slop. I saw a very nice young polish roster get devoured by those two pigs. They ate everything. Bones, feathers etc. A while later a young turkey flew into the pigs pen. They ate it to. Butchering time was near but you could see the pigs eying any chickens that hopped into their pen. Apparently they got the taste for fresh meat.
