And that is the result . 14 chicks of 25eggs ,but i could say that was 100% sucess because the other eggs were not fertilized. not even a single dead before or after hatch. Its not the arduino the most versatile machine? 
i found that the incubator with 2 fans its quite accurate , i check all the incubator positions with an precise thermometer and its quite good +-0.2ºc
IMPORTANTE NOTES:
-In the last 4 days before hatch i decreased temperature 0.2ºc every day until 37 - 37.2
it´s recommended for have a better hatch rate.
-I find this app usefull :http://homesteadapps.com/app/free/hatchchart/hatchturnsche.php
