Breeds such as the Welsummer, Leghorn and Ancona’s don’t usually go broody at all but many other breeds will. Hens can become broody around 2-3 times a year usually in the spring or summer.
Dealing with broody hens pretty much depends on what you want out of keeping hens. If you’d like to breed chickens, have a cockerel or a fellow hen keeper with fertile chicken eggs you can use a broody hen to your advantage. However if you’d like the optimum amount of eggs, it’s best to discourage the hen from being broody.
