And I've noticed if a pig find somewhere he likes he will continue to go back and go back no matter how hard you have to work to get there. Especially when there's food, like your duck food. That's how we ended up with one of ours. Neighbor got it thinking about having an indoor pig until it began eating her drywall and carpet because .... well it is a pig and we just leave it outside with a bowl of water in a bowl of food. He determined he liked our goats food and really liked our other pig company. And he would return on a daily basis
