when do hummingbird eggs hatch
When the ambient temperature gets too hot, female hummingbirds will beat their wings over their nests to cool their eggs or hatchlings. The eggs normally hatch in about 16-18 days. Depending upon the species, hummingbirds can have up to four clutches, or nesting attempts with eggs. But not all eggs hatch and not all babies survive. Generally, a mother hummingbird will not abandon her eggs or hatchlings. If she disappears, something probably happened to her. They have a tough life.
