Tonight one of my chickens disappeared - the other two (smaller) were still inside the run, door latched when I went to gather them. No signs of entry or struggle. The only thing I can think of is that there are natural divets in the grass creating a 1 or 2 inch dip below the edge of the run. Could my chicken (about 12" tall, adolescent healthy and round) have wiggled out? Do people steal urban chickens? Any answers? Also, is it possible to get a lost chicken back? We did a search of bushes, trees, and fences around the house. Are they smart enough to come home? This is my first try at chickens and I seem to be screwing up royally.
