Usually my wife takes care of the chickens, but as it has been so cold, I wasn't working today so I went out to feed the chickens and ponies. When I went out to feed the chickens, I took some feed into their coop and all but one chicken followed me in. The last hen couldn't jump up into the door so I picked her up and brought her into the heated garage with me with some feed as I figured she was sick or something. I put her in a cardboard box, with a handful of food and a little dish of water and then went out to feed the rest of the chickens and dethaw their water etc. I came in with a dog carrier from the barn and figured I would put the sick hen inside there for a couple of days in my garage which is warmer and see if she gets better. When I picked her up to put her in the dog carrier, I noticed that her feet weren't moving at all. I tried to move them and they are stiff like a board. It has been very cold here the last day or two in WI, with temps in the low teens to single digits for highs, and lows below zero. I don't know if she was sick and went outside and couldn't get back in and stayed out overnight, but if she has frostbit feet, is she going to die, or should I put her out of her misery so she doesn't suffer? As soon as I put food in front of her, she started to eat but she can't even move around at all in the pet carrier; she was just leaning back and forth. Was wondering if there's anything I can do for her other then keep her in the heated garage(40 degrees) for a couple days and pray for the best.
