I came home from work to 4 wild duck eggs in my incubator, A friend of the familys wife took them from her work. They had ran the mommy duck up, dont know all the details, anyhows they are now in my incubator. I candled them and they look to me to be about 5-8 days old. I've never incubated duck eggs and need to know what temps and humidity I should keep the bator also how long do duck eggs take to hatch??
