I hope your girl is feeling better this morning. Unfortunately, I don't have any direct experience with worming and can't answer to that. I do have reasonable experience giving meds in general.
If you need to give liquid medication in the future, you can try adding it to a small amount of a high value treat (like cat food), but ensure your patient has the appetite first and will actually take it.
If you're only giving a small amount of liquid, and your patient won't take food, then I'd get it into their mouth by slowly smearing it along the crack of the beak. The liquid will naturally work its way in and be swallowed. Beware this is a slow process, but it's one I've had to do for chicks.
Hoping the educators will be along this afternoon to help.
