When I treated mine I also treated for capillary worms, so I gave it for five days. One study says to treat gapes you give Safeguard for three day and one book says five, so I would go with five and get as many worms as possible. The Safeguard dose I use is 0.23ml per pound for five days. Liquid or paste, doesn't matter, it's the same amount. Dose for a five pound bird is 1.14ml, but it's okay to round up or down a little.
Thanks K. I write it all down. with all your doses and instructions.
If any of my numbers look off for whatever reason, please do say something!
