What is this?

We've just candled this egg for the first time, and saw these two dark lines. not sure what they are. but the embryo is still moving inside. the egg is day 19 if that helps.

Keep your fingers crossed for this one. Dark areas are often from a bacterial or fungal infection. Never seen it in two lines like that, though - it's usually a circular area. I'm hoping it's just an anomaly.
