OK, I've had her in the house for about a day. She is doing well. My vet said every 5 to 7 hours dip her feet in warm water with one teaspoon of salt and a med she gave me. She said its less likely she will lose a foot or toe. Do to that it is only first degree frostbite. She said it will heal with in a month or two. But, my other gals won't get this too. I moved them to the garage. In my old rabbit hutch. I have four chickens. Rose, nugget, red, and Carmel renamed frosty. Frosty is upstairs in my room. She is in a towl and has a heater, feed, and water. She is doing better. Thanks guys. I found that my sprinkler pipe has a leak and it goes under the coop. It keeps raising. It was 12 degrees today. She was eating the bread I put in there this morning. She must have been in it for a while. But, once again thank you. If I have questions I'll ask.
I'm glad you were able to seek vet care.
I hope she heals and recovers soon, thanks for the update.
