Easter Eggers are a sort of mutt. They are a cross between a blue-egg layer and usually a darker-egg layer. The combination can include many different crosses. It's nearly impossible to answer that question without knowing the cross. But, if you have info about or, access to, older siblings of the same parents, you certainly have a better shot at determining if they tend to go broody. Hatchery birds, because they don't want them to stop laying, usually have the broodiness bred out of them.
