Talking about a wormer Valbezan and Safeguard . I use Wazine for both pigeons and chickens . It's time to re-worm , can you get these at a Feed supply store ? Most things like this I can cross use , but for the pigeons I have to recalculate doses . Smaller bird . Do these kill gapeworm and tapeworms ? I have ivomec that is formulated and all I have to do is put two drops in my pigeons . Got some Vitamins and Electrolytes at Tractor Supply and I had to lower the mixture to 3/4 to 1tsp per gallon of water for my pigeons . I know we need to alternate wormers so they don't get a resistance . I alternate from Novalsan to Oxine when I dis-infect lofts and coops for the same reason .
