Christian names? Given names or first names please! We can't go assigning a religion to them at this age, despite the fact that we do it to our own children. Although the "bleeding heart" would lean toward Christianity.
No, what I tend to do (right or wrong- advice gladly taken) is to leave the the newly fledge young in the aviary until the next set of eggs hatch and are almost ready to fledge and then transfer to a holding cage. Seems to work although sometimes I think they are a bit little however they are fully independant, eating and roosting by themselves etc etc.
