I am looking to add one or two hens to my Sumatra flock. I am not looking to add more Sumatra's to the flock just yet. I simply want one or two hens to help me hatch out eggs, so I wont have to use the incubator all the time. I am look for breed that is really friendly and extremely broody. I wish to use them to hatch out eggs instead of an incubator when I can. I was wondering what you think a good breed would be for me and why?
