Hello, I have had chickens for about 5 years and peacocks for about 2. And i've never dewormed them before, Should I and what should I use? Also is there any other vaccinations I should give them while i'm at it. I may have a chicken with coryza, she has a runny nose and her shavings keep sticking to her nose, also she didn't want to eat much, I'm not possitive its coryza but if it is can my other chickens catch it? and what can I do about it? Thank you
