I live in Iowa and winter has come early (it's been cold, snowy, rainy, and windy all week). It's my first winter with my goat babies and I'm getting confused by the things I'm reading online for prepping the barn for winter. I'm including pics of the inside of the barn. Here are my questions: 1. I know it's bad to have drafts, but how do I given them access to get outside without leaving the door open, which then creates a draft? 2. I close the doors completely at night to prevent predators, but have been leaving one or two of the windows open for ventilation. Is that enough ventilation? 3. Should I put some sort of insulation behind the plywood 'walls' and if so, what kind would be safest? 4. My boys have barely gone outside this week because of the weather. I'm worried about them not getting enough exercise or getting bored. Should I just let them be where they want to be and not worry about it? Should I put some sort of toy in the barn for them? 5. Anything you see missing inside the barn that should be there for them? Thank you for your help! I'm such a newbie and just want to keep them safe and healthy.
