I don't have a roo myself, but I would if I didn't live in a city neighborhood, and I could free range my girls. We have predators even in the city. Plus, fertile eggs would be good to have around for broodies. As I've found out, breaking broodies is no fun for anyone. Fertile eggs don't taste any different from regular eggs and as long as you collect everyday, you shouldn't get any weird surprises in your eggs, as they need certain conditions to develop.
