vets have confirmed blackhead....most of my flock of turkeys have gone
vet doesn't hold much hope for the others, im trying apple cider vinegar in water and cayenne pepper on the food.
vets advice is to carry out a course of worming every 3 months for all the birds. Use foot bath between going into and out of where the turkeys are. and using something like Virkon to make sure everything is fully disenfected before trying again.
he said once its in the environment its very difficult to get rid of, as it can be transferred through earth worms and also turkey to turkey.
I don't want to give up just yet on turkeys so will give it another go. I wish id paid more attention in school in biology lessons as it would help make more sense of how these parasites actually work - back to the learning board.
