Dear Worried,
1st ISOLATE that chicken. Most diarrheas are bacterial, & spread very easily. Dispose of all soiled litter where it cannot infect other chickens. Wash your hands before & after you handle the bird & its litter. Get some cheap "hand disinfectant" to use liberally on your hands when you work around your "sickie". You don't need this diarrhea either, & some bacteria also like people & dogs.
2. Keep in a draft free, reasonably warm area. Most birds can tolerate "cooler" but not "draftier". If bird is "on the floor" make a dry straw nest a& be sure it is protected from drafts, & attacks from other birds.
3. Antibiotics - it sounds like E. coli diarrhea, or coccicidosis - aviary antibiotics are available from vets, McMurray Hatchery - added to drinking water. Sometimes
TSC carries them, but not in my area. The typical one used is neomycin or auromycin.
4. Give clean drinking water twice a day, keep drinking bowl clean. White vinegar & water rinse does great.
5. You can even add a little 1/4 tsp to 1 pint water to drinking water - it helps the diarrhea. Add a bit, maybe just under a tablespoon of brown or white sugar to the water so bird is getting some easily digestible calories. Gatorade works too, but diluted 1/2 strength.
6. Be patient. Don't put the bird back into the flock until it has no diarrhea for at least a week, and has regained it's strength.
Good luck. Some make it, some are too weak. I hope yours is one of the strong ones!
