My hen is a bourbon red, not yet a year old(I got her this past spring), and she is half the size of my 3 toms(2 bourbons, 1 chocolate). About a week and a half ago my hen started to get sick. I had recently moved her from our chicken lot to the turkey lot with the toms, and we had some bad weather. It rained about 3 inches or so, we had some strong winds, and low temps. Instead of standing under shelter they walked around in the rain and stood in the mud and then they roosted all night with the wind blowing on them. A day or two later when it was time to refill the feed, my hen was acting strange, she was uninterested. She just stood huddled up, shivering. When I offered her some feed from my hand she picked up a few bits and then let them fall out of her mouth. I separated her from the others and put her in a cage in a building, off of the cold ground and blowing wind. The next day when I went to check on her she was very lethargic and I added a heat lamp to warm her up. She still had not been eating from the looks of it the next day or so, but was drinking alot of water and sleeping alot. The other day I opened the cage to see if she would come out and walk around, and when I returned she was walking around slow like she was lost, and was very unbalanced like she had vertigo. I offered her some scrambled eggs yesterday and she refused to eat anything again. When she goes to drink water its like she can't see and will miss the bowl, so I have to hold it up in front of her face and move it so her beak will find it. She seems very dizzy when awake, and sleeps unless I am physically interacting with her. When I hold her she will go to sleep and I have to give her a small shake just to get her to wake up. I gave her some electrolytes in her water and today I used an eye dropper to get some raw egg and crushed cat food into her for protein because I can't get her to eat anything else(using the dropper I only got her to take a few drops). Her waste looks like watered down scrambled uncooked egg(even before I tried to feed her some), and she doesn't go very much at all. I have researched blackhead and it's symptoms but I don't know if that's it considering the timing(right after a rainstorm and night in the cold), and the fact all my turkeys were raised with the chickens. Plus the other turkeys are fine. I just don't understand. Besides I thought tukeys infected with blackhead usually die within a few days of showing symptoms, and my hen has been sick well over a week now. Does anyone have any advice on how I should treat her, or any ideas on what could be wrong?
