Hi, I have 5 mallard eggs that have been incubating for 18 days, I candled them lastnite & they look good. Their parents were killed by a raccoon ( their parents are my profile pic, they were my babies) I was devastated when they were killed. Can anyone tell me what the hatch time is, some sites say 28 days some say 24-26 days???? This is my first time incubating & I don't want to lose these eggs..
