Hi, maybe you folks could help me with something I've been puzzling over. I read that the requirements for a good goat shelter are that it is draft free, but also well ventilated. I will be needing a shelter with a locking door to keep the (future) goats safe from predators. So is the ventilation provided by, say, louvered windows or vents towards the top? Is that enough ventilation at night to keep ammonia and other noxious gases from harming their respiration? Is the "draft" problem about ground level winds? Of course the shed would be open during the day, but I was concerned about night time air. Thanks, L PS I know this post might really belong in the barnyard section, but I wanted to get as much feedback from you experienced and knowledgeable folks as possible.
