We're just boarding him, so we're not the knowledgeable ones. We've provided a dry barn stall w/fresh hay to eat and access to water and pasture, but now that we're having an ice storm, he's just out there standing in the pasture, kicking around the ice to get some grass. What's wrong with this guy? I'm kinda kidding...I assume animals know what's OK. But since I'm concerned, I'm asking here. Is this OK? Even if it's not OK, I'm not sure what options we have. It's 20something out there, so not crazy cold. Thoughts?
