Hey Zovick....you should be sitting here with me at the Daytona Hilton bar right Now!If it was laying eggs, it is pretty safe to say it is a female. It is very probably what is called a Stinkpot (Sternotherus odoratus), though it could also be an Eastern Mud Turtle or Florida Mud Turtle. They are not too friendly as a rule and have fairly long necks. Stinkpots have yellow or light stripes on the sides of their heads and necks, the necks of other two are more unicolored.
Eggs will probably hatch in 60-75 days; of course this depends a lot on you incubation temperatures. I would say 80 degrees is plenty warm for those eggs, even a bit lower is fine, too.
