We have the same issue, and I was considering it a couple of weeks ago.
However tests with bees, which also drink nectar found that they starved
when fed sugar water with CS in it due to it killing their flora which
are necessary for digestion. Without evidence to the contrary, I would
not recommend doing it.

A quick Google didn't turn anything up so I thought I'd ask the list:
Do you have any experience or other knowledge to indicate whether CS
would be helpful/harmful/neutral do hummingbirds? The reason I ask is
mould can be a problem in hummingbird feeders and I was thinking CS
might help stop that (not sure on this either, just thought it might
inhibit mould too---please correct me if I've missed the boat). I'm
not sure what kind of digestive system hummingbirds have (their diet
is nectar and insects) and whether CS would be compatible with their
needs or not. All feedback/ideas are welcome. - Walter
