You might get more answers if you made a new thread. But all you can really do is fence the chickens in or fence in what ever you are trying to save. You can try cliping their primary flight feathers on one wing to see if that stops them from going over.
Yeah they are doing their thing..It's snowing pretty hard here.. and what are the silkies doing? Standing in a crowd, about 2 feet OUTSIDE of their dry coop.
