I've tried to put the wormer on a piece of bread using the 1cc dropper and feeding it to them - but my chickens would not eat the bread. It's perfectly good white sandwhich bread that I eat. They wouldn't even eat the bread without the meds on it. What alternative way is there to worm with Valbazine? This time I used Ivermectin pouron and put drops on their backs using the polysol dropper - but it seemed like alot of dropping and I worried that I gave too big a dosage.
