Pros: Hardy, friendly, easy care, decent layers of big white eggs, plus they make me laugh!
Cons: They will roost in trees if given the opportunity, but keep them safe in a coop at night.
If you have to build a separate coop in order to keep Polish, get busy because they are better entertainment than TV. Love all the beautiful colors, and my roosters are so nice I never worry about them being aggressive with anyone. Great birds for kids, and everyone that sees them here on the farm wants one or more!:-)
