Today when we went out to close the chicken coop we found our tan chicken we got this spring on the floor being lethargic and she has a blueish tint to her comb. She is obviously not feeling well. It has snowed all day long and they did not really come out of the coop today, I did not shovel it since it has been steady snowing the whole day. She is with 6 other girls who all seem to be fine. The wheather has been nasty and I am not sure how well she has been eating, her chest feels a bit boney. I brought her in on my porch and put her in a cage I built when they were young to warm her up. She did eat a bit of food when we brought her in. (layer crumbles) I tried to get a pic of her. any help or advise would be really appreciated, this is the first sick chicken we have had.
