Hi all. One of my young birds quickly collapsed and died after being given ivermectin. I'm dosing them for worms and mites as well as using permethrin spray for feather mites. I've been dosing 0.2ml per bird. He went paralysed in one leg, then the other, then full collapse in under 2 minutes. I may have mixed him up with another bird and dosed him yesterday as well as today, but I still wouldn't have thought that was enough to kill him. My other thought is he had such a worm burden that killed him. Any thoughts welcome.
