I want to improve my chances of having broody hens by diversifying my flock. I currently have NJG, SLW, EE, BR. What should I add to make sure I have broody hens for next year? I have already added some Hamburgs this year which I am sure will not improve my chances. I can get silkies, Houdans, Sumatras, Faverolles, and Araucanas (not Americauanas) locally. Which of these will fit in with my current flock and make good mamas'? By the way, I also need breeds that will survive the Arkansas heat and humidity.
