One of my hens is ill. She showed signs of distress just before I went out of town for job training, and she looked worse upon my return on Thursday evening. I phoned our vet, but of course they don't treat chickens, but they DO have a liquid to treat coccidiosis, which we determined my hen does NOT have.
Robyn, preening her feathers, before becoming ill last week.
I had several options which could be costly, but the first to try as far as I was concerned, is twice a day Penicillin injections. The recommended dosage for a laying hen is 1/4 cc....and so, I caught Robyn quite easily and was able to administer the dosage into her thigh muscle with little trouble. The vet said that bacterial infections are easily cured within a few days with help of Penicillin. I hope this does the trick!
