I'm probably wrong, now she is outside sitting but earlier she did do the crouch thing a few times and she had her behind up high and looked like she was trying to push something out..when I watched an egg laying last week for the first time, the female did the same thing but it went on for hours before an egg finally came!
So April 23rd last year, wow that is far off. They've been mating up a storm though, I know it takes time but that's a month away?!
