My chickens tested positive for cocci. Which treatment does everyone think is the best (at what strength) and how long would the egg withdrawal time be? It's kind of a relief to know what's going on. I have pullets, 1 1/2 year olds and up. None of them are dying although my older bantam rooster is fairly sick. Cocci does explain the variety of symptoms we have going on. I have 1 1/2-year-old Buff Orpington hens that haven't laid eggs since before the summer heat. We sell eggs. We have about 40 hens that should lay and are getting anywhere from 14 - 19 eggs per day. My husband is about ready to start killing hens! Uggghhhhh!!!! I really need something that will work and hopefully quickly (safely). I would like to not have a huge egg withdrawal time if we can help it! Thanks for the help!
