Yes..treat all chickens.Do I just treat all of them because it might take a while to figure out who it’s coming from. Is it safe to treat. It’s weird because I gave the medicated feed for a certain amount of time to try to prevent this but they actually just got off their medicated feed recently
Make sure this treated waterer is the only water they have available to drink.
Mix 2 teaspoons of the liquid Corid with a gallon of water.
Mix a new batch of water every 24 hours.
Give them this ^ for 5 days.
Then after those 5 days mix 1/2 teaspoon with a gallon of water and give them this lower dose for one week.
