first off, I wanna say that from what you've written, both in the other threads about Percy and this one, I think Percy is doing really well. To explain why I think he is doing just fine, I'm going to respond to each of the things you've raised here point by point below:
Eric&Rebecca wrote: I know I've posted about this before but our parakeet is still being really... disinterested...
well, I think this is actually what the grasskeets are like. Theyre really not anything like regular parrots in behavior, really. While I can't speak for Red Rumps in particular, I do believe that the the Red Rumps personalities are similar to that of other grasskeets like the Bourkes, Princess parrots, Scarlet Chesteds, Rosellas, etc. This whole bunch (and my Toby included) is pretty much known for their independence. They are perfectly content not interacting with you. Yet they like to be "near" you. Thats what Toby is like. he is happy sitting near me for a long time. he often looks quite disinterested doing this. but if I get up and go to the next room, guess who's following me? Toby. and in the next room, he might find a place pretty far away from me to sit, and stare out the window. but if i leave that room, he will follow me again, maybe sit on my shoulder and nap (if Ringo is busy elsewhere or in his cage). Then fly away and do his own thing, and ignore me for an hour.
so this is just the grasskeet personality. they are VERY different from budgies. I've had a number of budgies in the past, and all of them were SO much more interested in me than Toby. some were even clingy, wanting to sit on my shoulder all day. the grasskeets are really a different kind of bird. They do not seek interaction from people as intensely as regular parrots (budgies and tiels included) do. In fact, sometimes they want to be left alone to just do their own thing. Toby often doesnt want any direct attention from me. During those moments, he prefers to just sit on a high place and watch the household, ignoring me, Ringo, my husband, everybody. Just doing his own thing, napping, etc.
Eric&Rebecca wrote: i've been reading about how they should behave and ours doesn't and I feel like a bad bird owner...
goodness! from what you've posted thus far about both Edmund and Percy, I would rank you among one of the most conscientious bird owners i've ever encountered! i think any bird in your care is destined to be a happy bird, because you really have made a lot of effort to make both Edumnds and Percy's life really great, checking on small things, etc. so even if Percy doesnt meet your expectations , please dont see that as a reflection of your care for him. i think you're taking wonderful care of both your birds!
and also (and this is a word of warning about EVERY single species out there) there's no cut and dry formula for how a particular species ought to behave, it depends on a lot of things really, just SO many factors. in the case of Percy, youve only had him for a few days. a birds personality doesnt come out until the bird feels ready to reveal it. and Percy is parent raised besides. a parent raised bird is going to take a LOT longer to get adjusted to living with a bunch of bipedal mammals who have long appendages and binocular vision

. Percy has not been imprinted to humans. but as a bird of the psittacine family, he has the intelligence to learn, over time, that he's in a safe and good place. but its going to take him a while. and remember, even if he does feel safe and good about his world as a bird, he is a grasskeet - a parent raised budgie or tiel that gets acclimated to a new home is going to behave a LOT different than a grasskeet in the same position. The grasskeet is going to be more independent - it is not going to seek your company as much as a regular parrot, even if it likes you and feels safe in your house. thats just how they are.
Eric&Rebecca wrote: We have tried letting him out the cage and he doesn't want to come by himself. We've left the cage fully open for 2 days, he didn't really show an interest in that- So we've managed to train him with the wooden dowel to get him out the cage.
i think using the dowel to get him out is fine.
Eric&Rebecca wrote: When he's in the cage, he'll hop down to the food bowel and go back. Then eat perhaps chirp a couple of times and then go back again to exactly the same spot on his perch. Then later on he will go hop down to the water bowel and again return to the same place. He sits there literally all day, he likes looking out the window but he doesn't really react to anything else. He doesn't hop around the cage but he still seems alert and healthy. He has pecked at his preening toy a couple of times but that's it.
Health wise there's NO fluffing up (apart from preening) and he eats enormous quantities for such a little bird.
all this sounds really behaviorally normal for a grasskeet. they have big appetites, because they expend a lot of energy.
also, not all birds like spray millet. Toby is a healthy bird, with a really good appetite. But he doesnt like spray millet, even when he's hungry. he prefers walnuts. each bird is different.
if Percy's eating well, and his poops are well formed, and his eyes are bright and clear and wide open during the day, and his feathers are not fluffed, and if he's not sitting on the bottom of the cage, and if he's not exhibiting any signs of typical illness, i would just not worry too much, and just give him some time to adjust.
Eric&Rebecca wrote: I just can't figure out what the problem is because he doesn't seem stressed :-/ ...This just doesn't seem right at all.... Austrailian grass parakeets are described as animated and active... Ours is just the total opposite and if that's ok then I'll love him all the same but I just feel like he's not happy or something.
really, from what youve written, he sounds healthy, and his behavior sounds really normal for a parent raised bird thats just arrived home from the aviary. although i havent met Percy and can't really tell, from what youve described - his little chirps, and the preening, the healthy appetite, etc - he sounds REALLY happy to me!!

the grasskeets are pretty layed back birds. theyre really not demanding at all, they are just SO different from regular parrots. sometimes this comes across as lack of interest on their part. but i do think Percy will warm up within the next two months. its going to be a long time frame like that, because he is parent raised.
here's a way to put the whole thing in perspective. there's actually very little difference between Percy and any of the outdoor songbirds that come to visit your garden. So in the beginning, having him in the house is going to feel like you have a wild bird in the house. Over time, he will learn to appreciate your company, but its not going to be an automatic thing, like with a handfed. Yet there are countless benefits to him being parent raised, which i think you will discover in the future.
