Flighty baby quaker

I'm not surprised he doesn't know the step up.  Breeders are generally not known for keeping babies long after weaning, and that's about the earliest anyone would start training step up.  How old is your baby, and what is his weight?  It's normal for a bird to lose a bit after weaning, and if he's a blue quaker or another variant he may be naturally smaller, but anything seriously outside the norm should be checked by a vet. Is he eating and drinking okay?

Give him some time on the behavior.  You're right, he's just gone through a whole lot.  He's been ripped away from everything he's known in his little life and experienced who knows what discomforts on the trip.  Who could blame him if he's very, very stressed.  Species are different, and individuals within a species are different, so comparisons can be futile.  Let him settle in a bit and be calm and soothing around him, but I wouldn't wait too long to start working gently with him.  You basically have to bring him up, like his bird parents would have.  

If you you have any concerns about his health, take him to an avian vet.  I would take him anyway, just to get things off on the right foot.  Good luck with him, and keep us posted!  

so I'll try this again...sorry, just learning.......
not sure how this works. Had to create an acct to answer. You need to call this breeder! ANY reputable breeder will answer any and all questions. This sounds like an older bird to me that didn't get much attention after weaning. I mean...it may be what some people consider a baby and sold as a baby but was just put in a cage after weaning. If a buyer has a problem with one of my babies I will go as far (within reason) as to go to their home in order to place my babies in the best homes. Did u get a Quaker or a conure? Banded or not banded is a preference. I personally band but there is nothing wrong with a bird that is not banded. Did u pick this bird up in person? Not sure. You say county but did you mean country? What state are you in? Even though not my baby I would be willing to help...it's all about the bird. ANY bird. Not just mine. Not sure again....how this all works. Send me an email at

Make sure to tell me who u are and why u are emailing. From there I'll give you my cell so we can text. This is all assuming you are in the US. This is an older post. I hope you are nothing coming along.
Some babies wean pretty quickly and some are a little stubborn but there is no reason that a baby doesn't at least know the beginnings of what 'step up' means. No reason at all...
unless little trouble makers non of my babies get clipped until leaving and that is at the descression of the buyer. I do recommend clipping though. 
I just get so aggravated at dishonesty. It give all the truly good breeders a bad name. It's not about the money. Well.....maybe a little. I like to have 'stuff' for my birds and they like it too. Bird toys, perches, swings, t pees, lots of good food, etc. I have 3 buildings (I've been told no more, I'm out of control) full of 'stuff' for my birds and only 15% of that is taken up by cages. I am so lucky to get up every day to work at something I love. That is the kind of bird breeder you need to look for in your area. They are out there. Grrrrr....I am ranting....sorry 
there are also many good bird stores out there too. You have to ask around for personal experiences. Usually they are ones where when you walk in there are baby birds everywhere out of their cages, playing. Most pet stores will leave them out all day under a watchful eye. This gets them acclimated to all sorts of things so even if they do get older after weaning they are still very social babies. So don't discount pet stores.
