Same, my spring hatch I had nearly an incubator full of fully formed chicks dead in there shells. I was keeping it at 50% the first few days and 70% the last 3 so I assumed they must have drowned. I was pretty bummed. I did get 7 to hatch, but I was incubating about 30 eggs. Now I'm back to getting my 95% - 100% hatches with the dry incuabtion!
