We used to have a couple of goats, and one of the survival things we had on hand was Vitamin B Complex for a boost if need be. What I was wondering is if I could put this in my chicken and ducks water? Our male Pekin duck has developed a cough, because our weather is cold one day and warm the next. I mean not just cold I mean 30's during the day to teens at night then high 50's the next day. So the birds are up and down. Even though they have a 200 w light on all day and given warm water to drink this is no match for fluctuating weather. Please help if any ideas on using this vitamin.
