When is the latest that a pigeon egg will hatch?

Question

So far it's been atleast 20-21 days since the first pigeon egg was laid, and Ive read everywhere that its on average for wild/feral pigeons to be 18/19 days...

Answer 1

Usually they hatch on 18 or 19 days, but if the parents don't constantly sit on the eggs it may take longer. I would wait to about 25 days before you throw them out.

Answer 2

Chances are they're infertile.  Don't worry.  I can almost guarantee you that the parents will abandon the nest in the next 24 hours anyway. They normally only sit about two or three days past the normal hatch and then begin a new breeding cycle.
