I have hatched chicken eggs but never duck eggs and certainly never Muscovy. I have saved up 12 eggs from one hen.. thats all I have and I thought 12 days was enough for the eggs to sit, so .. an even dozen it is. I have the temp set, its practically raining in the incubator, Humidity is at 88-90% is there any suggestion you all can add before I stick the little suckers in their new home for the next 35-38 days? Oh.. and do you think I could wait and save even more eggs? or should I stop at 12 days 12 eggs?
