The three mistery eggs I had were not Ring-Neck. Way too big.
The room where you candle should be dark - no lights at all. Use a mini mag on tight focus & you will likely see the forming chick moving, the eye & blood vessils clearly visable. You may want to give it a couple more days & look again. If in doubt still, break one open. Sounds like you have lots. Let me know what you find/see. I'll be away from the early AM of the 25th for weeks or months at a time. Working in the bush this summer.
Won't be shipping to the States. Try this place for any birds you may want. Scroll down to message board and click on it.
