Haha its fine I like the questions, but yes they rarely go broody, but when they do they get over it in a couple of days, so if you want chicks an incubator would be the way to go.
This is true it is truly your decision, and your dog will be a great source of chasing off predators. I experienced my huge Delaware Roo chase off a fox so its probably a good Idea for a rooster just for extra protection.
