What I have is liquidYou're using the suspension version, and it will settle out of water, so here's what you do:
Mix one ounce of Safeguard in one cup water. Then mix with about 15 to 20 pounds of feed. Cut this down if your flock is very small. Feed for three days. Repeat in 10 days. Egg withdrawal is two weeks.
It's much easier using the paste version. If you can exchange the bottle you bought, it would make life simpler. You only need to squeeze out one pea size dollop per chicken. Repeat in 10 days to be sure you got all the worms that may have hatched.
