temperatures diffrent breeds can handle

[All About Chicken]

I’m in southwest PA foot hills of the Laurels. I have a question if someone can answer? I’m thanking of getting some jungle fowl build a open but covered roost and put them in the wooded area of my property to run wild. Still maybe a problem with egg layers even though they would be ¼ mile away. My real concern is the winters how sensitive are Jungle Foul to temperatures?
