I bought some Tylan to treat my chickens. I know that they are sick, but I do not know what they have. I am awaiting test results from the vet for possible MG The symptoms are: runny noses (some clear and some yellow), bubbly eyes, head shaking, and some coughing. I have been putting 1/2 teaspoon with 1/2 gallon of water. It is the only water that the chickens have access to. They have been doing this treatment for 2 days, but I have not seen any sort of progress. I have been cleaning the noses daily as well as the eyes. What should I do? Is there something that I can do that will help them get better sooner. I do not want them to die. Please help. Any advice would be awesome.
