We've got 3 Sow's and 1 Boar. Our 1 Sow 250lbs "Black Pig" is very aggressive toward our Boar -175lbs. She tore up his ear and who knows what else yesterday after breaking through the door between their areas and cornering him in his pen, while we were at work. One of our other sow's "Big Pig" 240lbs was "taken" by our Boar 2 days ago, with no problems. Do I need to just let them duke it out? Currently they are seperated with seperate lodging both in the barn and both outdoor spaces. :/
