How Long Does It Take For A Purple Martin's Egg To Hatch?
At least 2 weeks.
It takes about 15 to 17 days to hatch.
Purple martin eggs hatch approximately 16 days after the last egg is layed. The female begins incubation at that time. It may take two or three days for all the eggs to hatch. Baby purple martins are born with no feathers and fledge about 28 days after hatching.
