I know this is a chicken site but i have recently been given a duck egg which was laid a few days ago. Im afraid it will die and not hatch. i have tried to make a homemade incubator but i need step by step help to do this right. im really looking forward to having this duckling hatch. I do have the egg somewhat enclosed to were there is heat and warmth from a light i have set up. I dont want to over or under heat the egg. Im trying to get the egg at around 99-100 degrees like i have read. I have been rotating the egg a couple times a day. I was told a story recently too, were this person had found duck eggs by a pond and tried to hatch them theirselves. it put me in a panic b/c they said the ducks died and the eggs had rotted. but they put their eggs in socks and by a heater. thats different from what i have but im still really worrying. i dont want to try this then weeks later find out that time was wasted and the duck died. Like i said, the egg was laid a few days ago and when i put a flashlight to the egg ive seen the air bubble thing. i know its too soon to tell if there is a duck forming in there but so far all the dark things i see in the egg is the bubble and really thin dark lines on the inside of the shell, it reminds me of veins. I hope you all can please help me. im needing to know about humidity as well. thanks.
