My Chinese goose has been sitting on two eggs for about 3 weeks now. I took them in to look at them with a flashlight and couldn't see through them except a large clear part at the top. Is that good? Or are they rotten? The male and female were getting along quite well a while back But theyre each under a year old... And also, how long can goose eggs be left unattended in 70* weather and be okay?
