I have a Banty Cochin that hatched one egg yesterday she still has 5 eggs left, I checked today and the five are still not hatched. How long do I let her sit on the eggs. I don't know how to candle. I think that her eggs are staggered by a day or so. I don't know. I didn't think that they layed this late in the year, yet this cold. Any advice would be appreciated.
