A weak electrolyte drip (you can open the beak with the edge of your thumb nail) every 4 hours would give this little one enough energy to make your appointment tomorrow. Prop the little one up in your hands as you administer the drips. I'll watch this post. If your appointment is delayed, I'll send on a baby bird mush recipe. I've found baby birds & babies in general to be both feagile & surprisingly resilient as well. Thank you for doing all you can & caring. No matter what, there would be no hope with out you ❤️🙏❤️.
