I have a big female whose last shed was on 3/26/09 and immediately after that shed I could have sworn was glowing. She was lighter and there was tons of blushing on her head and neck. They also locked 2 or 3 times when I thought she was glowing. Now it's 5/4 and I have still seen no ovulation. She doesn't look gravid either, and is still eating however not as viciously as before. What's happening? Thanks
