This is my first set of eggs. I've got 2 broody hens doing a fantastic job of keeping 8 eggs warm. I've not yet understood how people create sets of eggs that all hatch on the same date (so if someone could educate me, that'd be awesome on that!), so I will have to refer to my eggs by the date they were laid. I didn't have a great flashlight until today. I grabbed 1/17, two 1/19's, and my 1/20 and brought them inside. 1/17 does not look at all as advanced as the 1/19's and my 1/20. I've read that sometimes eggs can just stop growing. I smelled the egg. It doesn't smell rotten. There's a part of me that doesn't want to give up and terminate the egg. But there is a part of me that is scared it's a bad egg and will explode all over my good eggs. Put it this way, we could see movement in the other 3. I could see an air pocket, what looked like the eye, and a mass in 1/17. That's it. I could not see veins either. Suggestions?
