So my flock eats as much as they want, have new fresh water every day. I have some ducks and chickens but my chickens have loose stools and are skinny. Does anyone have a good suggestion on deworming and doses to do so? I am very interested. I have access to most if not all medications that can be used for deworming purposes just need a practical way to deworm many birds. My chickens are having respiratory symptoms as well - chemotic and runny eyes, heavy breathing. I have not lost any due to the respiratory issues but have lost a couple for no apparent reason - I'm thinking parasites. Any help would be appreciated.
