I thought the ducklings were dead in the shell... Its day 31. No movement. No sound. I cracked the shell and it was still alive!!! Not anymore because I killed it! HELP??? There was quite a sizeable yolk... I have 15 more. I cracked open 3. One was yellow foam (super rotten). The second was kind of a bloody mess. But this 3rd was alive... I am so sad and worried. I guess I should just wait it out. I can not believe I killed it. Any suggestions??? To the best of knowledge the temperature and humidity are ok. They are Indian Runners. Thanks... I need some Duck Lover Support!!!
