Last year was Teela and Azazel's first year as a breeding pair, and he was so slow to start doing his duty that the first egg was infertile - Teela's hormones reached the right level before his did. But this year he's more on top of things (literally) and it looks like every egg will have the opportunity to be fertile.
That's good because I want more pearl chicks. They gave me a pearl girl last year who was the first pearl chick I've ever had.
