I found two of my cockatiels mating in July. I removed them from the others and my female laid 5 eggs in the nesting box. The first egg was laid on 8/1. She continued to lay eggs on 8/3, 8/5, 8/7 and 8/10. My husband and I held a light up to the eggs to see if they were fertilized. We could definitely see blood vessels and an air sac. Since everything looked good, I was expecting the eggs to begin hatching last week, but nothing. I candled the eggs again and 3 of the 5 look like the embryo stopped developing early on. The other 2 look like there is a large embryo, but I can't see any movement. How long should I leave the eggs in the nesting box? This is the first clutch for my birds. Could the parents inexperience lead to the issues?
Thank you for any advise.
