one of my hens has hurt her leg or foot while free ranging in the yard. There is nothing visible (no bumble foot) but doesn't like me messing with it. I currently have her resting in the small coop I raise chicks in and use as my sick bay but it is in the 20s here and I'm worried she is too cold. two options, I can leave her there and add a heat bulb or bring her in the house in a small dog crate. will I stress her out more if I bring her in?
