At least, one of my girls is. My Jersey Giant every single day gets out of the coop, and I have no idea how. We boarded up the wall we thought she was getting through so I think she must be flying over the fence. Every day she gets out, lays her egg outside, walks around the shed (and it's a LONG walk), to the gate of their run and waits patiently for me to come let her back in. I don't know how she does it but she's outsmarted DH and I. At least I know she lays an egg every day! Atta girl!
