If in fact there are eyeworms present in her eye, they would be dead by now.
I magnified the photo and I dont believe you're dealing with eyeworms. The white blob in her eye might be pus, but I'm not sure. Only you can tell or see what it is. It's not eyeworms.
Mix a 50/50 solution of albendazole and water and flush the eyes with it. Then give 1ml of the liquid mixture orally to your chicken. Repeat dosing the chicken 1ml orally in 10 days. Good luck.
