On average, how many hens out of twenty should go broody each year? I have twenty hens and I am lucky to have two go broody per year. A fellow chicken farmer who lives near me keeps between 20-30 hens and has 3-6 of his hens go broody just in spring and early summer! How can I get more of my hens to go broody? I keep ameraucanas, speckled sussex, barred rocks, RIR-Columbian Rock crosses, and EEs. My friend keeps the same along with cochins and black stars.
