How did he do that? #sol21

I love watching the cows on the farm where Mike lives. I’ve named several and I’m starting to think one (Rosie) now recognizes that name. When I’m traveling up and down the lane where I can see them, I often roll down the window and check on them. Some of them have become almost like pets.

Coming down the driveway, I caught sight of two of the cows munching on hay. However, when I looked closer, I noticed that the younger cow was inside of the round bale feeder. I had to stop the car (and snap a photo!). How on earth did he do that?

When I returned later, the young cow was no longer in the feeder. Again, what happened? How did he escape?
