Can anyone help with mixing and dosing of this drench wormer? https://www.vetpoultry.com/products/prohibit-soluble-drench-powder I believe you mix the packet in one quart of water? What is the dosage I then give orally to a flock of 5 and 6 pound birds? How many consecutive days? Repeat in 10 days? Do I store the mixed batch in the fridge and does it last for 10 days? Sorry about all the questions, I am clueless about this stuff. Trying to use something other than Safeguard. Thank you everyone!
