How long does it take to hatch a pigeon egg?

The normal incubation period is 17 days regardless of outside temperature. It takes all-most two weeks or more, it depends.....if temp is adequate means 35-37 degree then it will hatch in almost two weeks otherwise it will take more time. In case of abandon eggs by their parents himself means that egg is dead otherwise u can also help them in hatch by maintaining the humidity and temperature.
17 to 20 days
