Do you think there could be an issue with the doghouse being too humid? Should I make air holes? I'm also wondering if the geese are getting spooked at night. If a coon or anything walks by, they hit the water. Maybe there is too much going on to ever sit on a nest for very long. That's a good idea about marking them. I wish I had thought of that before I had 20 of them lol When they go broody, how hard will they fight to stay on the nest?
