From these pictures, what colour/mutation would you say this chick is? I know she is very young to be able to tell, but anyone have some educated guesses?

Mainly I'm asking if she now looks Cinnamon and/or Opaline.

 

I am thinking grey normal

I agree with Dave

i don't know what the parents are but the chick is a normal and of the blue line.

if you look closly around the upper legs and tail there should be a few blue feathers growing. check it out and see which shade of blue it is :bow:

Look at the two or three pin feathers that come out just above the tail. They arent tail feathers, but they are among the first coloured pin feathers to show up anywhere and they are located just above the tail feathers on the back of the budgie.

 

I agree, looks like a normal grey. Blue series at least.

I'd say normal sky blue but the colour will show in a couple of days
