Ok I know this will sound stupid to a lot of people but I have NEVER killed anything intentionally in my life so I feel soooo guilty. Here is what happened. I set some Olive Egger and BCM eggs recently and have been having a terrible time with my incubator. I had the temp set and running for a week before the eggs came and had the incubator in a windowless temperature maintained room but the temps were all over the place. I had tried candling the eggs a few times and couldn't see anything at all and started to think that they had all died because the temps in the incubator kept jumping really high and then jumping really low. I decided to just sacrifice an egg and break it open to see if it was completely cooked or just bad. Well it was developing and the little heart was beating. I felt sooo bad afterwards. The poor little thing was trying to live and I killed it.
