greetings and welcome aboard.I have read your thread and I also agree with our experienced staff here as well.it takes a great deal of knowledge and experience,dedication to raise budgies.unlike chickens,the bonded budgies needs to be in top healthy condition and atleast a year or more older.
Any number of things could go go wrong and you must be prepared incase the female abandons her eggs,chicks etc.
Not trying to sound harsh,but compassionate plea .
But if you take the time and study,read and get well prepared over a period of time.perhaps one day after having all the necessary things and having the proper knowledge,then you can let them breed.
my best opinion is learn from knowledgeable breeders ,reading ,studying .
you would want healthy and in top condition budgies for breeding to prevent deformed,birds that have French molt and so on.
Blessings and thanks so much for joining us.you came to the right place indeed.
I wish you and your budgies many happy years together.I hope wasn't sounding harsh, I just have greT respect for all and hope I can help in any way.Blessings always
