This clutch of blue-to-blue parents was the only such successful pairing in the US for 2004 that I am aware of.  Sadly, these were to be the last offspring from Aquaman, who died in the early spring of that year from RI complications.  The dark babies were characteristic of his previous offspring, and they will carry on his genetic heritage.  In the mean time, I am working with mom to lay more than five good eggs!
