I have a pair of orange wing amazons, my female laid 4 eggs, as of this past wednesday, it has been 29 days of incubation since the first egg was laid, and none of them hashatched as of yet, as far as i can tell they are fertile, what should i do about this, take them all out and see if they will lay again or what, or wait until time has past for the last egg is supposed to hatch, someone please give me some advise about this.
