What In the World?

I was in the pig pen feeding and watering. I also was petting on my babies. I look over and Athena is on top of the pig pen. I tried to run her off but she is pretty stubborn. I look back later and she is literally in the pig pen. I was a little nervous about how the pigs would react but when I got close to Athena, she ran out of the pen. What in the world was she thinking?? I wonder how often she has been in there??
