Well, even if I'm very open on questions of identity, that's a relief to know

They will be 16 weeks this Sunday, but Piou-piou was always about five weeks behind in growth and obviously this has altered eventual sexual characteristics.
@Marie2020 : I have used Artemisia last year for the chickens in an infusion mixed with thyme twice a month. I put about one hand full of leaves in one and a half liters water, and add a teaspoon of honey as it's very bitter. I also propose plain water next to it so they are not forced to drink it. It is toxic in high doses so should not be given too frequently. I don't think you can give it to cats and dogs, not that it will be dangerous for them, but it's so bitter I doubt they will have it if it's not transformed in a form that is palatable to them.
And remember it won't be any use for an animal that is infested- if you actually see the worms, it means they have too many to be treated naturally.
