I've used it before but I didn't mix mine I just used the aerosol. John, do you still spray your eggs with TekTrol?
Yes. After I place the eggs into the plastic setter trays that go into the setters (incubators) and just before setting them I liberally spray the eggs with the
Tek-Trol solution. I dilute Tek-Trol with water according to the label. It completely covers the eggs and is much quicker then dipping them. When I first tried it a few years ago I started with just a little mist and was afraid of overdoing it, but I haven't noticed any negative results and it only takes a few seconds to do. I especially feel very comfortable using it because it includes hatcheries, setters and hatchers in the list of many uses on the label.
I use the same solution to clean the setters and hatchers. The setters get cleaned once before the hatching season starts, but the hatchers get cleaned weekly after each hatch.
