It takes 30 days of incubation for eggs to hatch. Winter temps also play a factor, goslings generally hatch in the spring, but some can hatch in late winter, just depends on how cold it is. Good luck!!
Thanx much! I will make sure and be close by the first week of next month. The "winter" here has not been much, spring flowers are popping up, most signs say its over, but one never knows. I hope she gets a few anyway it would be great to watch them grow!
