Asylum, those are adorable.
Luvmybob, you need the story of my first hatch in the incubator. I got the incubator in the first place because I tried to order eggs for my broody Australorp x EE, who was sitting on ping pong balls. The eggs I chose couldn't ship because the hens stopped laying. There were all sort of problems. Finally, BD got turkey eggs for her and I bought an incubator on the off chance that the other eggs ever arrived. The day the seller (a very nice lady I still correspond with) told me the eggs were shipping, I ordered a second dozen from another lady, to help fill the incubator.
It took a week (this was a hot July, also) for the first eggs to arrive. The second eggs arrived within a day or two. I put them into the incubator about 5 days apart. I bought a second incubator. I candled throughout, but I had no idea what I was looking for and I just kept the eggs in the whole time. Day 23 passed on the 2nd eggs and it was time to lock down the first eggs. As I was carrying the carton across the kitchen our puppy jumped up and caused me to drop an egg.
It splatted on the floor. No candle wax would have helped, but it was no great tragedy. I had white and yolk on my floor. My only worry was keeping the excited puppy from eating the obviously infertile/quitter egg. I managed to get it cleaned up and decided that instead of locking down the eggs, I would take them and candle them. They all looked clear to me except for one. I put that one in the incubator and went outside with the carton and a small stone.
I think my intention was to see what the candling actually meant. I was reasonably sure the eggs were empty. They were. Then I went back for my day 23 eggs. Out of the 12, I had one small embryo, one DIS, and a lot of empty eggs. Talk about discouraging! I never wanted to incubator again.
There is a little more to the story. I didn't mention Scraps. Scraps was a little orange chick who was never born. He was a bantam from our own barn. I put his egg in while it was still warm from being laid and he was on day 21 that same day I was cracking open eggs. I decided I would save his life. I couldn't. It was too late already. I haven't really changed my incubating practices. Scraps and the one DIS just weren't meant to be.
If I'd stopped there, with my 0 hatch rate, 33 chicks may not have hatched at all this year.
