Hi i have 2 hens I think. I want to get a tom and bread them this spring. Do they need a nesting box like chickens. will the hens sit on the eggs or can i put them under a chicken or should i get a incubator. I have the hens in a coop/run right now they have lived in of the passed few months. I want to let them out but dont want them to fly away or get in truble with dogs or other things. If i let them out would they go back in at night like the chickens. i have heared after a year of age they dont fly as much any truth to that. if there is any other tips please let me know thanks for all the help. p.s. the are a x burbon and spanish black.
