If she is heat stressed I read you can bring her inside and put her on a cool wet towel and when i did this to one of mine she stopped panting and was fine shortly, and I returned her to the outside after dipping her in a little cool water also. If she is egg bound there are remedies, i haven't had this happen to me but be sure to google it if you don't find an answer soon here. And in the bigger picture if she is bound they say it's related to nutrition, so i added oyster shells. Good luck, I hope it's something simple like just the heat !
