I have a duck egg on day 28 just now (8am this morning) with no pip either, Its alive and the egg is moving. Your just going to have to hang tight..like me
I am on day 20 also. I am going to tell you the same thing all the wonderful people on here told me. Step away from the incubator..... Sit on your hands, bake a cake, get on BYC play a game, plan a hatching party and make lots of food and make it a big one. I am the same way. This is what everyone told me. But I feel what you feel. Nervewracking. Good luck
*raises hand* I'm guilty of touching them. We are on day 20 as well. I had them in a cut down carton and just took them out to hopefully get to see them roll. I had to add a wet towel for humidity as that had gone down to 60%. That was my justification for doing it... No pip so far but now I'll leave them alone lol.
