Ok, if it is Coryza, Can I eat them or the ones ot showing signs of it. I have the State vet coming to test them. Could not find any Tylan 50 so I got Tylan 200. How much should I give them? Should I give a shot to evey chicken.... Do I have to change needles for every chicken...... I hope it is not but I guess I will find out in a week or two from Tuesday..
