Rejected baby after flying the nest

[libby92]

Got budgies from someone who couldn’t care for them, so new to the budgie world. So there is a baby that after it flew the nest, the parents and other birds don’t go near it, is there any chance that once’s it’s a fully grown bird that they will accept it into their flock? It’s smaller than its sibling that emerged the following day. The parents are fine with the second born that’s flown the nest. I just want to know if it will be accepted once it’s fully grown

I don’t think there is anyone who could guarantee any budgie behaviour. You would need to introduce them back to one another slowly, and under supervision.
