Hey Andythescot,
My girls didn't batt an eye at the 8 degrees we had a couple weeks ago. I have no idea what the wind chills were then. Where in Central MA are you??? I'm in Hudson, we could be neighbors!! What kind of chickens do you have??? I specifically picked hearty breeds since our NE winters can be so fun.....not!! It's a nice one out there today, the girls are out bouncing around in their run picking thru the dry leaves I put in there ystrday to combat the MUD we had w/ our mini thaw. I think I'd rather take some cold over the mud......
