I have a white rooster more than 2 years of age, since 2.5 months his right eye is swelling and has shifted his neck bone towards right and sometimes seizures occurs and his comb and wattle becomes black and it becomes difficult to breathe. Also tears comes in his eyes and becomes bubble and congestion type sound comes from his mouth. Vet has said he is suffering from new castle disease. Now seizures are very less but saliva comes in his mouth and becomes bubble and makes it difficult to breathe and it is very frequent. What should we do so that saliva stop covering the entire mouth.
