I put my 5 duck eggs on lockdown tonight. Three of the five look like they have broken into the air sack. Does this mean they will be earlier? They are all moving but the ones in the air sack are really moving. They are not really due till Sunday but since they were into the sack, I went ahead a day earlier. I filled all chambers with water, put three small containers of water under the screen and then I soaked two kotex in water and layed it in there. Hope for the humidity. Kotex really swell up with soaked... lol.Hopefully will post pictures in a few days.
