Hand feeding
Sometimes it becomes necessary to hand feed baby finches or weakened birds.
Typically, I mix a small portion of water and the powdered hand feeding formula and feed the baby birds (or sick bird) with an eye dropper. Sometimes, they will reject my attempt. Often, I will place a drop on the side of the closed beak and the finch will eventually take partake. My experience has been with Pretty Bird Hand Feed Formula because that is what was locally available and recommended to me.
