I put two eggs in the bator sunday to see if they were fertilized. I Just candled one egg and didn't see too much. Not sure what to expect. I saw the yoke at top with what looked like a few vessels on top of yoke. Nothing in center of egg. I decided to break it open and take a look. Saw a very small red spot that looked like vessels. Should I be seeing more or is this correct. Looking for advice since I don't want to start collecting eggs if they aren't fertile yet. Thanks for your help.
