I have a large pig pen with two 6 month old pigs in it. They have always been gentle pigs around me. Often my chickens fly into the pig pen to pilfer pig food. Two days ago I discoverd my rooster in the pig pen several bitten. Now I went outside this morning and I discovered a hen missing. Sure enough, I looked in the pig pen and I discovered a foot. They are eating my chickens!! Are these pigs dangerous??? I often have children on my property. I cannot keep pigs if they might somehow harm a child. I'm very concerned. Can anyone offer me advice? Do these pigs need to be put down?
