We have a goose who went broody end of December. She had one of her own eggs and a bunch of duck and chicken eggs she was setting. At one time she was over a dozen. A chicken egg hatched but she was too heavy for it. When she was off the nest a few weeks ago I checked the eggs. Her egg felt empty. A couple days later when I went to put them up it was laying in the middle of the room and was completely cold. But she is still setting on the other duck eggs. I went up a while ago and found a dead duckling outside the nest. We think the chickens get to them when she is off the nest. So husband had me bring remaining eggs into the house. They are in a very big deep Tupperware bowl with bedding in front of a space heater. Good news. One egg has a little hole and is peeping. So what are the odds out of 10 eggs I can get a few ducklings? Any suggestions? Should I spray them?
