I'm not fantastic with my exact mutation work of budgies as I'm new in the game, but we've had our aqua blue opaline hen (Bonny) lay her first egg yesterday. Now her mate is Clive, double factor spangle (yellow) although If you look extremely closely he has a tiny faint green marking perhaps, on his chest but it's almost impossible to notice unless you're really looking for it. We were wondering what they may produce..
Ill endeavour to get the best pics of them I can. Thanks a lot
