My young stock have recently grown into themselves and what i at first thought to be an equal number of males and females has turned out to be a vast majority of females. When all this birds were young and showing no signs at all of pairing or colouring up on the cere I let them all in the avairy where there is one pair nesting. And I watched closely and saw no signs of trouble.

 

But now they are starting to mature and showing signs of pairing...Is this a very bad idea to have these unpaired females[about six to eight months old] in the same avairy as my pair who currently have two big chicks in nest? I have been watching and no signs of trouble yet but i know these things can go wrong very quickely.

 

Any Advice?

This is one for the breeders, it is obviously starting to worry you that there might be trouble. If it were me, I would take them out and leave the breeding pair to it.

I had a youngster (female) same age or less as your "spare" females. She entered a hens nestbox and killed the chicks and the mother of the chicks died also. I believe she entered the nestbox as a nestbox was still familiar to her, but a fight ensued and the family were killed. It is always best to keep the breeding pairs away from "spare" budgies. Even 12 week old young females have got it into their heads to take over a nesting box and bonk all the boys and have babies. I have experienced this in my aviary. Now I only mostly have breeding pairs in breeder cages. Also your male who is busy fathering babies could be swayed by the other females and desert his family. That happens too.

Budgies don't remember family relationships when it comes to breeding so you may also end up with siblings pairing up.

Just my advice from my experience
