It was so cold here last night and this morning, (4 degrees) My girls are healthy and happy my barred rock hens (2) did well they are walking around, eating,and wanting out of the coop when I opend the door but one of my RIR hens (I have 2) didn't want to eat or socialize like usual she just wanted to huddle to me I don't want to bring her in because im afraid she will go into shock from such a temperature change but she seems to be very cold ,the funny thing is she is the biggest one we have. I took them some warm rice and veggies hoping to warm them up a little but like I said she wanted nothing to do with it what should I do with her? do you think maybe she just wants to be held or is she really very cold? Thanks
