To take a short break from the colour schemes, I will give you some other budgie facts:
The female budgie lays her eggs one at a time and this happens during a period of one to two days. The number of eggs varies between four and eight!
The first egg will generally hatch after eighteen days, and each chick will hatch in the order the eggs were laid. During the first few days, the mother budgie will spend all her time sitting on her baby budgies to keep them warm.
