morning all, im in southern in. and far as ican tell my chickens have crd. treatment is tylan or gallimycin. the problem im having is I cant find a vet to treat chickens local and i guess i need a script for the meds. i dont know what to do. wonder if i should put whole flock down, it would break my heart. i have new babies coming in a few days. ( dont count ur chicks before they hatch) and they will probably be infected too. my flock is about 45 all together, including my guineas. does anyone know if this affects guineas? all info would be helpful thank u
