I have been pairing a Hypo male and a 100% Hypo female for about 2-3 weeks now (3 days on, 3 days off). I have been working about an hour away from where I live. I check them at 6:00 AM and then at 5:30 PM, 11 1/2 hours between. He is always laying on top of her or beside her but I haven't seen a lock. Do you think there is a good possibility that with so many hours between the times when I can check in on them that I'm just missing any locks that may be happening?
