My 3 duck eggs are going into lockdown on April 7th! I want to make sure, right now, that I know what to do. Last minute questions don't seem like a good plan for incubating. Teehee. -How high should the humidity be for duck eggs during lockdown? -I need to remove the second vent plug. How can I keep the humidity up high enough, since the humidity rings are full already? -Am I "allowed" to stick my hand through the window to add more water to the rings or anything during those 3 days? I know I had more questions... They seem to have slipped my mind. Any other tips/info on lockdown would be awesome!
