My worst "broodies" are 2 bantam Frizzles. They are broody about 1/3 of their time. My Rhode Island Red goes broody about once a year. My Easter Egger and 2 Welsummers haven't gone broody yet. My hens are young, 1 and 2 year olds.
All good here. Letting my chickens patrol my garden for bugs and worms. I just keep my young plants "caged" with poultry netting until large enough to withstand "chickens on patrol". I am busy and chickens are happy:wee
