Remember, you are starting with the hardest possible scenario - shipped eggs over long distances, change in altitude, first time, etc. If you survive this, you can survive anything!
You've done a great job so far, and remember that no amount of perfect incubation techniques can resurrect scrambled eggs.
Next time try some local eggs, or maybe some shipped from WY or an adjoining state, and you will see much better results.
Or you can be like me and keep ordering eggs from far away and only getting 1 chick per dozen set.

(Although my homegrown eggs hatch great!)
