If you mean Easter Egger, my EE hen just finally went broody at a year old and she is one of my best mamas yet! All my other broodies are bantams, and Snakehead, as she is called, has the advantage of being quite large which makes her a great protector for her babies. I was a bit worried because for the first week and a half she wouldn't leave the brooder with them for more than five minutes, but maybe she knew something I didn't and one of the babies needed extra time. She also readily adopted a baby that hatched a week later. I'm so proud of her
Are your pullets red sex links, too? I'm not sure how broody they tend to be. It's great that you are already okay with the idea of hatching some boys though! Many people fall in love with hatching or buying chicks but aren't prepared to address what to do with the boys.
