Is this ok for poultry

Poultry fan

I have 4 hens. Can I use this on them and if so, how much should I apply? I usually use a medicated feed, but would prefer to use this so I know they are all getting the same dose.

This product is only licensed for use in pigeons so I cannot advise it's use in poultry. If you are looking to worm your hens then I recommend Flubenvet or Flubendazole 1% as these are both licensed for use in the species.
