Thanks so much for the info!!
Got another question if you don't mind..
Am I more likely to see a lock at night, or during the day. Im working tonight 7pm - 7am, and tomorrow night 7pm - 7am. When I check on them during the day they just seemed coiled around each other like a giant cinnamon bun (haha couldn't think of anything better to describe it.. LOL). And how long do they stay locked usually?
