Okay. This is it. My two muscovies are sleeping out in their new coop tonight. For the past week or so I've been letting them freerange longer and longer, to the point that they have only come inside to sleep, after dark. But I'm STILL worried about them being cold. I hope I got the ratio of ventilation vs. draft right. And my coop is not insulated. I've filled their area with the bedding they're used to, and am putting some food and water in for tonight. But geez, from where they've BEEN sleeping, they could hear us walking around, see us around the corner, hear the tv going. Tonight it will be quiet. And dark. (Not that dark, I've put a small light about 15' away, so that it's not PITCH black). This is ridiculous. At least I'm not worried about predators. Their coop is solid, and up off the ground, and will be locked, and is inside a chain link dog pen that I've been neurotic about covering with hardware cloth, poultry wire, and a partial roof. I know this is best for them. And all of us, lol. But the worrying isn't very fun. Thanks for listening!
