My chicks are in a huge Rubbermaid water tub in my greenhouse when they are wormed. I am paranoid about birds running out of water , so I keep 2, one gallon waterers in with my babies. On worming day, I remove one, and add the Wazine to the remaining one.If the babies finish that water off in 12 hours, I give another dose that will last until morning the next day, so they get 24 hours of Wazine.Agreed. On that note, when you do Wazine with the chicks, how do you administer it? If you add it to their water, do you allow them to drain the waterer over a course of days, or do just give them access to it for a 24 hr period?
