I have a Rhode Island Red who became lethargic & stopped laying in Nov/Dec. & spent $350 + 8 hours at the world renowned ISU vet. hospital. They gave me a sulfa med & "guessed" she had coccidiosis. While on the drug & after, no improvement. I gave her some rooster booster & in February she was back to her old self. Then in May: stopped laying, pale comb, lethargic, lost a lot of weight, won't hardly roost, pooping neon yellow. She eats & drinks somewhat normally. Her crop felt impacted-large and firm/slightly squishy. I took her to an avian vet-$150 who "guessed" parasites & sent me home with a wormer. I wormed her and she became slightly more active, the crop feels more normal. About 8 days ago I started Corid & I thought one of her wings looked less droopy (it drooped for about 3 days, I thought it was broken) & she was getting around & eating better, still not roosting at the top. She got up on the top roost to my surprise 2 nights ago. Then last night she didn't roost, she was on the ground with her face in the dirt. I put her in a spare nest & this morning she looked dead. She couldn't keep her eyes open or stand, her head was flopping down. I tried to give her some sugar water & she couldn't swallow. I layed her down to die. Everytime I checked on her, she looked dead and twisted up, but surprisingly, when I touched her-she'd stretch a little. When I was sure she had to be dead, I went out & she's just sitting there with her head up. I put her on the ground & she acts like she doesn't feel good, but she's STANDING! I got some baby vitamin & sugar water into her. I'm waiting to pick up an antibiotic, just to try.
