eggs not fertile

I think that the eggs are fertile, but your incubator might be the problem. What are you using for a thermometer? If it's not correct, and the eggs are getting overheated, it will kill them immediately. Far more eggs are rendered infertile by overheating than by too low of a temperature.

I'd suggest that you purchase a ready made incubator if you are really interested in hatching eggs. They don't cost much, and can save you a lot of heartache. Good luck!

 

jhm47 could be very correct. This link shows pictures of fertile eggs, so you could crack a couple, check them, and maybe take care of that concern. At least you will know it is not the eggs and you can concentrate onyour incubator.

Thermometers are not always accurate. I suggest going to Walmart/Lowe's, wherever, look at their cheapie thermometers and observe the temperatures they are showing. You'll probably see a pretty good range of temperatures. Pick one in the middle and that agrees with most of the rest. Then take it home and compare it to your existing thermometer. True, this does not guarantee that the cheapie will be accurate at 100 degrees, but it should be pretty accurate around 70, the probable temperature at the store. This might tell you that your thermometer is not working or give you pretty good confidence it is working.

I don't have any good suggestions on making sure the humidity is right.

Good luck!!

 

if you can crack an egg open, take a pic and post it. we can help you tell if its fertile !!!

if you have a roo your eggs should be fertile so like another person said something else might be the prob !!

 

Even if the bator was not perfect the eggs would start to form. Have you checked for chicken mites?

 

I agree with Danny, the embryo will start to form even with improper temps, unless the bator is hard boiling them! What day are you checking the eggs? If the hens have extremely poopy buts that can prevent the roo from doing his job.
