Answer:
its possible but the first couple of days i would consider putting your second budgie in a separate cage and after 3 to 4 days later move both of your budgies cages closer and closer every day and when you do that for a couple of days you can put them in the same cage but first you have to decide which cage you are gonna put them in put them in the bigger cage because if you have more than one bird they need more space well i gotta go hope this helps bye!!!!!!!!!!!!!
