I have 7 hens that have gone broody this year and I need to pick 4 of them to keep, and sell the rest to make room for my spring pullets. My question is, if a hen went broody in April, will she likely go broody early next year too? And a hen that didn't go broody until July, will she likely go broody late next year too? And what is the likelihood that all of these hens will go broody next year? Pretty good?
