My son just got a pair of ringneck doves. The sellers weren't sure of the sexes, but I did a LOT of reading. I was sure we had a male and a female. The male does the typical bow coo, the female preens his face and engages in "beaking", and I saw the male on the females back in mating position. BUT, I found the first egg on Saturday. It looked like the female dropped it from where she was sitting on her perch. I removed the shattered egg. On Monday, there was an egg in the nest box. I removed it and replaced it with a dummy egg. They've been incubating it. Then today (Thursday), I found another egg! I thought doves layed eggs in twos. Any ideas? Could this have happened bc the first shattered? Or maybe the dummy egg isn't fooling them? Or could I have 2 females, in spite of one acting male?
