is there and easier way to tell if a turtle is gravid wait what is gravid?

Gravid is if your female is "with eggs."

The only real way to tell is her behavior becoming restless and touching in the soft area in front of the hind legs.

There is no need to post the same question three times. Just write all of your questions regarding eggs in one topic, that way you get concise answers and you don't have to search all over for all of your posts.
