Congratulations on your eggs!! arty: You are in for quite the exciting adventure!
Once the first chick hatches, you will get to see how different they are from budgie chicks.
From the moment they hatch, we are able to tell right from the start if they are green series or blue series.
Green series have orange downy feathers and blue series will have white.
Judging by the parents' colours, most likely you will have some cute orangey babies.
