My Cayuga has been sitting on 10 eggs for the past 4 weeks. (There were originally 12, but one disappeared and the other got broken.) I was beginning to think that all her efforts were in vain. However, after reading about candling, I tried it today and it seems that 6 out of the 10 seem viable. I'm not sure about the other 4, but since they don't smell bad, I figure I'll leave them. One of the 4 is pushed in on one side, but the internal membrane looks intact. Can that one still hatch out or should I discard it? Also, if it's true that only 6 eggs are good and I end up taking the others away, will the mother still sit on that smaller number? Last of all, how long should I leave the eggs if no hatching is taking place? Will the mother eventually give up and leave or is it up to me to remove the eggs? Since Mama Duck and I are both new at this, any helpful advice would be much appreciated!
