My tiels just hatched out 3 new babies a little under a month ago. They all live in an aviary and live with quail. I have a nesting box for the quail and the momma tiel thinks it's her nest box so she just laid an egg in there. She has stopped feeding the babies but the father hasn't stopped yet. Should I take the egg out? I have a feeling they will abandon and not feed their young. Please help! I can also take the nest box out if that will help keep the mom from going broody.
