Is it safe?

[colorin]

I have two gouldian pairs breeding in a 2x2 m. aviary. Their first clutch (fledged a month ago) remain in the aviary with their parents and the other pair, and there have been no problems of agression at all. All adults tolerate chicks and chicks still follow their father wherever he goes. In a week time the second clutch will be fledging, and I don't know whether it is safe to leave the chicks in the aviary when the younger fledge. Could they show agression to their younger siblings?
I like having them all together. The chicks are already "softly-singing" and learning the courtship skills from their parents, and I guess it's good for them being around the adults and learning the proper "behaviours", but I'm scared I might find an injured fledgling or something like that

I would very much appreciate any advice in this matter

Extremely doubtful they will hurt the others they may give the odd peck as a pecking order issue but they are a natural flocking bird.the main concern would be to ring them so you know who's who.

Before I had my other aviaries I had all my birds in the one aviary and didnt have any problems with aggression between the young or the young/adults other than as Buzz said, the occasional pecking order spat and maybe some open beaks stand offs, nothing dramatic.

thanks!
they have rings already, so that's not a problem.
I can't wait for the young ones to fledge! It will be interesting to see the difference in size between the younger chicks and the others!
