This morning while going out to feed and collect eggs, I noticed one of my leghorn hens huddled outside the pen and very lethargic. My leghorn constantly fly out and roost on the rails outside of the coop (in the process of fixing it) and typically are very athletic and hard to catch. She let me walk right up to her and pick her up. It's been really wet and cold the past 2 weeks but the girl's have held up nicely thus far. I brought her inside next to the fire and noticed her comb is blueish on the tips.
Any insights and tips would be very appreciated.
