The Safeguard or Panacur (both are 10% fenbendazole) dose I use to treat my peafowl for cecal and roundworms *only* is 50mg/kg (0.5ml per 2.2 pounds). Based on that, my peafowl get:
Large adult male - 3ml
Large adult female - 2ml
Small adult male - 2ml
Small adult female - 1.5ml
Large 3 month old chick - 1ml
Medium 3 month old chick - 0.8ml
Small 3 month old chick - 0.7
Above doses are for liquid *or* paste.
For capillary and gapeworms, worm for 5 days in a row.
According to a study I read and the recommendation of a vet, the most effective Valbazen dose is 20mg/kg (0.176ml per 2.2 pounds). Based on that, the Valbazen dose for peafowl would be:
Large adult male - 1.05ml
Large adult female - 0.7ml
Small adult male - 0.7ml
Small adult female - 0.53ml
Large 3 month old chick - 0.35ml
Medium 3 month old chick - 0.28ml
Small 3 month old chick - 0.25ml
Valbazen is 11.36% albendazole (113.6mg/ml)
Note that I did not include amounts for chicks under 3 months, but that's not because they cannot or should not be wormed, it's because I need to look up their weights on my computer.
I prefer to work all of mine orally, but I can understand why some people don't want to, and I guess if I had to choose between food or water or food, I'd choose food. To do that I would guess the weight of my flock in pounds or kg and do a little math. I would then most likely put the amount of Safeguard or Valbazen needed in some water, mix well and then I'd use that water to make a mash. I think Zazouse puts her wormer in eggs?
Hope this helps,
Kathy
Edited to add:
Safeguard or Valbazen, dose once, then ten days later.
Edited again to say that one must worm for 5 days in a row to treat capillary worms and gapeworms.
