I had 8 eggs set and 4 were not fertilized. From 4 eggs 2 hatched and the other 2 did I get rid of. First time hatch and did a wild guess which eggs could be fertilized.
Great pictures of all the eggs with chicks inside. Keep posting them. We set our first hatch on 3/3 and if all goes well will they hatch nearly the same day as my ordered chicks.
Please keep posting this great pictures.
