Sorry for your losses.
If you can give more information, more help will be likely. Are they fertile eggs from your flock? Did you have eggs shipped to you? Did you pick up eggs from a local seller?
What breeds were the eggs?
Did you candle the eggs to see if they were developing? Or were the ones that didn't hatch- die at a certain stage in development or were they dead in the shell at the very end?
Did you use a hen or an incubator?
What did you feed the two that hatched? What temp was their brooder? Any pics of the set up might help too.
While I hardly have any advice on hatching eggs, I would make a post in the incubating and hatching eggs section. Im sure the nice folks there will be able to help you.
So many things contribute to a healthy hatch, from where you got your eggs, were they shipped, how were they stored before setting and of course the machine you are using and whether or not it was calibrated and settings were correct. @curlyp has left you with the link to our Incubation forums, definitely post there for more help.
