I mixed some tetracycline and oregano oil into fresh water for her today, and will repeat with fresh water for the next week. I also will use some Ropapoultry Complete in another waterer, too. Anything else I should try for her?
Fyi she is an old chicken, probably 3-4 and hasnt laid an egg in a year. But otherwise seems healthy and active. Does she need to go to the vet?
