Okay, now I am excited. Four out of five eggs have air sacks. I cannot tell about the blue egg, but I will wait a little while before deciding to take it away from her.
I took the chicken eggs from her tonight. I candled them and nothing. One was just put there today so it will be my breakfast in the morning. I don't think the other was there much longer than one day since I never noticed it before.
So I guess I should have ducklings in about a week? Given the mixes it could take longer. I assume that if one hatches she will still sit on the eggs and take care of a baby?
I sure hope this makes her happy again. I know she has not liked being alone. I don't think the chickens really helped her as much as a duckling will (I hope).
