Sassy the chick, is not developing properly. The owners of the
cam, consulted a bird rehab specialist who thinks that the poor insect availability is perhaps the cause of her delayed development. So the owners have put out an organic rotting banana to attract more insects for Phoebe, the mother to eat and provide to the chick. Evidently there have been alot of storms to reduce the insect population.

They are considering moving Sassy to a bird rehab center, but will leave her as long as possible in the nest. Phoebe is not sitting on the nest anymore but does feed Sassy and come back to shade her from the harsh afternoon sun. Reports are that in the morning, the chick is in significant torpor. (which hummers do to conserve energy).

I have seen Sassy exercising her wings, and that is a good sign.
But the consensus is that she hatched too soon. (the other chick died from hatching too soon as well).
