I'm glad you found him! I'd love to hear the story from his point of view too.
I had a hatching corn escape before. I had just gotten her and didn't even have a meal in her before she got out. I was away on vacation so had no idea how long she had been out. She was gone for roughly 26 days before I found her making noise in a grocery bag.
My wife is fond of one of my corns and constantly lets it get cozy in her sweater pockets or the hood. He got out once and I found him snuggled into one of her sweaters sitting on the dining room table.
