We are brand new to incubating. Just bought a Brower Top Hatch and our 1st eggs are at 22 days, no pip, no chirping, nothing?? I tried candling but they are so dark/full inside I just can't tell anything. How many days should be wait before we assume they are not viable? Also, I did kill one chick on accident. I feel so terrible. It was when we were candling and we are still learning. I thought it was a blood ring and thus would be dead. I cracked into a dish so I could examine and learn from my mistake. Well, it was an inch or so fetus with big eyes and I cold see the heart still beat. Everything looked "normal" and no smell or other weird stuff inside. I felt so horrible and I'm really afraid to throw out any other eggs in case I make an error again!
