I have tetroxy hca280 soluble powder. I'm trying to figure out how to do a small dose for my one sick chicken. I believe before I read for an adult chicken it is 1/4 tsp to 1 gallon of water? The directions are for large doses using portions of the pack. Any help with the math would be appreciated? I only want to mix up a small amount so it's going to do a couple of cups of liquid. Thanks
