It sounds like she had a very high wormload. She is now passing the paralyzed worms. I'd do some supportive care such as offering electrolytes in her water and providing a warm spot she can get to if needed (you can use a heat lamp for this).
I would also check her over for lice and mites, since she doesn't need to be dealing with those along with the worms, and treat for them if needed. Additionally, I would follow up the wazine treatment with a broad spectrum wormer such as Safeguard in ten days, since Wazine only kills roundworms, and she may well also be dealing with other types of worms too.
Also, since she was so badly infested, you can almost guarantee all the rest of your birds are too. Put Wazine in their water and also do a broad spectrum wormer ten days after the Wazine treatment finishes for them too.
