My budgie laid 5 eggs in summer it didn’t hatch even after 21 days. Again she mated and laid 5 more eggs. In those 10 eggs only two hatched and rest of the eggs were pushed down from the earthen pot. Why does she do this?. Is there any problem with her or with the environment she lives?. We don’t have any separate room to keep our flying friends. We kept them in the same room where we eat and sleep. We will switch on the A/C during night while we sleep. Does the A/C cause any disturbance to my budgies?.
