I am going through the same thing. We hatch naturally, under goose, and in the bator. This is however the first time I have heard a gosling talking to me before hatching. They are not do to hatch for 4 more days. The one egg was talking when i got home from work last night at 10pm. When I checked it at midnight, no I didn't open the bator, I just looked in, there was no talking. Again this morning at 6am, before I went out to feed the animals, no talking. When I got back in at 7:20, the egg was talking away. At this point I did open the bator to spritz the eggs and check humidity as I always do. I did not hear any clicking noise, just the peeping. At 11am, there again was no noise. I am a little worried because as I said, I have never had an egg talk to me before.
Am I doing something wrong? Is the humidity not right this time? It is a foam bator. We have used it for chicks, ducks and geese. The water wells are full. I do have a mix of eggs this time. In the past they have all been toulouse eggs, this time they are black african, toulouse, roman tufted and embden. I have 4 of each in the bator.
