i have some chicks that are 4 weeks old. they havent been outside but im seeing blood in ther droppings today. one is a little lathargic. the only thing i have at the house is wazzaine(sp) and terramycin. the only feed store i have here is TSC. i dont know if they have sulment. can i start them with terra. untill i can find sulment? how did they get cocci? i hatched them at home in a bator. they havent beem outside of the brooder but they are in the grage.
