dawg53, I would have PM'ed you but I thought others might want to read your response to this question: I was told by my vet to treat my all my chickens for "possible" respiratory problems because of my rooster's problem. She suggested my using tetracycline. TSC had it under the name Duramycin-10 (tetracycline hydrochloride soluble powder). So I bought that. 400mg per gallon of water each day for seven days. I also ordered a bottle of Wazine as you suggested for doing a one-day treatment for worms, and it came today. You also said that I should toss the eggs for two weeks. QUESTION: Would you consider putting both the Wazine (a poison) and the Duramycin-10 (an antibiotic) in the same gallon of water for just one of the seven Duramycin-10 days. Doing it like that, I would only have to toss the eggs down the garbage disposal for two weeks.
