I know a vet is an option, but who else? We live in the city but are surrounded by rural land-I have seen a usda office and I know we have an extension. Could someone give me the facts on who tests chickens, the process, etc. I am totally new at this, and I have some hens that seem ill and I would REALLY like to know what I am dealing with before I treat them and bring in more. :/ But, I don't know where to start or who to call and don't want to sound like a total idiot when i do!
