Green unknown paste in poo

[LaFleche]

Here in Ireland, I can't buy any suitable wormer for poultry in feed stores, at least in my area. I can only buy 'natural' non medicated wormers online and I question there effectiveness.

This would be the right dewormer, you can also use it for dogs, cats, fish, etc.
