A few days ago, my husband checked on my younger chickens (about 3 months old) and one was not moving around and was laying awkwardly in the run of the coop. Most of the girls were in the coop, due to the extreme cold (single digits with a wind chill of -7), with the heat bulb to keep them warm. He easily grabbed her and brought her inside for inspection.
She has no visible injuries. Her feet are not discolored or swollen. She is eating and drinking as normal. However, when she tries to stand, her feet cannot support her and she squirms around to get to her food and water. She makes normal chicken sounds and seems perfectly fine when she's just sitting. Her poop is normal.
At first I thought she may have frost bite, but now I'm not so sure...
