Hello, I am very new to this. There is a duck in our neighborhood who just had a bunch of ducklings hatch but she left 3 eggs behind and never returned. I took them in after ensuring mom wasn't ever coming back. They are currently in a makeshift incubator as the real deal was not on hand. Anyways on to my question, at least 1 egg is chirping, to my knowledge it started late last night and has continued periodically until just now (as I type) but there has been no movement or cracking of the eggs that I can see. Is there anything I should be doing or should I just leave them alone. Temp is currently about 98 and humidity is around 50% (I've read Muscovy eggs need less humidity particularly as they get closer to hatching.) THANKS!
