Could you please explain.
You are looking at a very old thread that has bad dosing information on it. Through many bird losses, we have learned that diluting medications is ineffective and leads to resistance making the medications useless. It seems that the old wives tale about putting x number of ml or teaspoons of Safeguard in a gallon of water will kill worms. This equates to a doctor telling you to put two tablets in a glass of water and take a sip, it does not work.
Medications are based on a prescribed amount of a drug per body weight. That is why you step on a scale when you enter a doctor's office, so they can determine how much of a drug to prescribe. It is no different in animals, drugs are prescribed per body weight. That is why when you are told to give three ml per adult bird orally it is meant to be taken into the body. When you put those three ml into a gallon of water and BTW Safeguard is not water soluble, the bird has to drink the entire gallon to get the correct amount of medication. Obviously, the bird is not going to drink a gallon of water that day and if it is really sick it may not drink at all.
So, beware of anyone that tells you to dilute medications, especially those that are not water soluble The following pic is from a vet reference book that vets use to prescribe from.
@zazouse would be the first to agree with my information if she will come back.
