I am thinking about adding some polish chickens to my silkie coop because of their small size and unique looks. From reading about this breed I thought that they would work great with my silkies. Has anyone had any experience with mixing polish with silkies? I also read that they are not very cold hardy. I live in a very cold climate, so should I pass on this breed? Anyone want to share general thoughts about polish chickens to help me figure out if I want to try out this breed?
