I can't help you with young as mine are all bought so I have had to rely on the breeders' honesty. But I choose to take them at their word. I am sure Sal & Jon can answer this question.
When buying a Kakariki in general, it is pretty much the same when buying any bird. Check to see bird is alert, check for dried/yucky poop stains, check their overall colour is good/even. They shouldn't be too frigtened of you - they are a gregarious bird. If you get a Yellow Crown - check that no red feathers intrude into the yellow - this indicates a hybrid which you most definately don't want! This link will show you hybrids which is where my boy who died xmas day landed (final photo) www.kakariki.net/modules.php?set_albumName=album14&op=modload&name=gallery&file=index&include=view_album.php
How do I tell if a kak is young? What do I look for?
Its hard to tell the young from old
I can only give advice on green kaks/pied.
The main indication of a younger bird is the beak.
If you look at the following pic,
/\ click to zoom in!
dad on the left has a silver colour beak with black tip. baby on the right(9/10 weeks) the beak is still pink at the top. Also around the nostrils is usually the last the last part get the red feathers(also in pic),i would think this last bit would go for yellow/cinnamons to. but as there beaks stay pink the first bit wont help .
If you can get hold of the bird to look, lift the wings and look for the fluffy down feathers. my baby has still got them at 10 weeks.
It's only a week after my bday. LOL It's part of the AFA Bird Convention that runs from 5-7 of May. The convention costs about $270 but the show/sale only costs about $8 I think. There are a bunch of us from other forums meeting at about 12.30, so it would be great if you could be there as well and anyone else who can make it. I'll get back to you on exact details of meeting time and place.
