My 6 babies arrived today after a 4 day journey. They looked sick when they arrived, so I gave each one a tiny drop of nutridrench on the side of their beak. They're doing fine now, but 2 look slightly weaker than the others. I don't think it's anything to be concerned about. So, the question is can I put some nutridrench in their water or will that discourage them from drinking or over dose them?
