Ovey! What a hatch I just completed. I bought 10 Wheaten Marans Eggs on eBay in early July and received 12 beauties! BoY was I psyched! So, I let them sit for 12 hours and then put them in my ECO20 with the auto turner. Sometime around day 7, the power went off in the ECO20 but the auto TURNER kept working. I NEVER NOTICE THE BATOR WAS OFF! I HAD UNPLUGGED THE BATOR BY MISTAKE BUT DIDN'T REALIZE IT FOR 36 HOURS+! I COULDN'T BELIEVE IT! HOW STUPID OF ME! So, I plugged it back in, pulled my chin up and carried on. On day 11, I did a check and discarded 6 of 12 eggs that were clear. On day 18, 5 looked good and a 6th had quit so I tossed it. As I took that one out, it collided with a good egg and dented it good, an area the size of a dime! Oh gosh, what a mess. But I kept my head and got a dab of Elmer's Glue on my finger and lightly coated the dent and surrounding crack and put it back in the bator for lockdown. And prayed... And waited... And sent positive vibes... And today, on the 21st day, I awoke to find out of the 5 eggs, four hatched! So, never give up on a hatch if the power has gone out! And "a little dab of glue will do ya" on a dented and cracked egg!
