Round & around the egg dish

Why is it that feathered kids (fids) go round & around a food dish when the food inside is the same?  Does it taste different from the other side?  I am guessing it is a case of the grass being greener on the other side, i.e., the egg being nicer on the other side.  Budgies sure don’t like to miss out on anything!

Here is a short video of the toyboys going round & around the egg dish:

Here is Atilla joining the toyboys…. clearly she needed to approve of both the egg dish AND the camera.

PS. I was not completely sure of the use of the words “round” & “around” so I have used both to cover all bases. 🙂
