Does the humidity matter so much, that it would kill the ducklings or prevent them from growing if not at the right humidity? Sorry if this is a little weird. I'm trying to hatch ducks and I need to know, because I'm having trouble stabilizing my humidity. Also, I tried hatching ducks a couple weeks ago and I'm sure they were fertile but they didn't grow. I checked the temperature ever day and turned them and everything and I have hatched guineas before... but I did notice that the humidity sometimes got off balance. Does it matter that much that it would kill the ducks?
