turtle gestations??

Question
June 29th a turtle came from our lake...and was busy digging where our lawn was to be...well eggs happened and tonight is the 3rd full moon since the laying...no signs of problems but how long should I wait..?

Answer
Between 20 to 350 days, with 2-3 months usually... assuming the eggs were fertile and the nest was not disturbed.

I am a bit curious about the phrase 'where our lawn was to be'. If the yard was sodded, rototilled, chemically treated, etc., it could have disrupted the nest or many other things could have happened to it. Even in a perfectly natural setting, many nests have problems.
