I usually do the Wazine for round worms first. Then 10 days later, I do Valbazen- I put 1/2 cc in a tiny piece of bread and they gobble it right up. I give 1/4 cc for my bantam silkies. With the roos who give all their food to the girls, I have to catch them and feed it to them with a syringe but it's not too bad, just pull down on their wattles (or beards for the Ameraucanas) and its easy to open their mouths. I switched to the Valbazen from Ivermectin last year because it kills more kinds of worms and apparently the worms are becoming resistant to the Ivermectin now.We observe a 14 day period of throwing away eating eggs when we treat.

Here is a good thread on worming

ive heard the same about parasites in horses. Due to people not properly rotating their wormers the buggers are growing resistant. Same with a lot of other things. Bacteria becoming resistant to penicillin and other antibiotics due to over use and not finishing them. Does anyone know of anything natural that will kill the worms? Tobacco is supposed to kill worms in dogs and people. I've never tried it tho ski I don't know.
