Well I got a incubator given to me a few days ago cause it was missing parts well my old one had just died so i took parts from the old one and put on the new one and i told the person that i had fixed it and they gave me a duck egg to test it with. so i just set the egg about 10 mins ago and i have never hatched a duck before i was wondering is it 21 days as well for them or what? and i know temp is the same but what about humidity?????
