I have a hen (Salmon Faverolle 23 weeks old) that I found not moving on 3 days ago. I let all the chickens out to free range in the yard for a couple of hours and she was fine. An hour after I put them in I noticed she was standing in the corner not moving. I assumed she was just resting. I went out again that night to close them up and she was in the exact same position. I had to pick her up to put her in the coop and on the roost. The next morning I let them out and she stayed on the roost. I did notice she had diarea but no blood in it just green and white very watery. No worms that I can see. I came back out an hour later and she still has not moved. I then took her inside and put food and water down for her, but she never touched either. All she does is stand there until she gets too tired then she will sit. Then she won't stand till you pick her up. After 24 hours, I thought it might be Cocci so I went and got Corid and added it to the flocks water to treat the entire flock just in case. I also started giving her water using a syringe. After 2 days she still hasn't shown improvment so last night I started feeding her with a syringe also so she can keep up her strength. I also gave her 2 warm baths and I put my finger into her vent to see if she was egg bound, but I felt nothing hard everything was soft. This is day 3 now and now she is laying on her side, and she will only pick up her head when you come by. I still gave her some water then laid her back down. PLEASE HELP I don't know what's wrong or how to figure out what is wrong. I think she might die today if I can't figure this out. I no longer think it is Cocci but I figure it can't hurt the flock to medicate them anyways. Just to be on the safe side. I have also wormed the flock but not the sick hen because I read that you shouldn't worm a weak chicken.
