Brothers

Hi and welcome aboard!
Special congrats to you for rehoming your 2 new friends ! This is a special time for you to make the transition comfortable for you and them as well. My lil guy, buddy, has a sleeper and a day cage along with a playgym all side by side with seed catchers. His sleeper cage is 20 deep x 24 wide x 27 tall. His day cage is 22 deep x 26 wide x 34 tall. Both have top perches one being a double. The playgym also has a top perch and a sisal rope attached to the ceiling from a hook that I also run a thicker chain across his span to another ceiling hook and anchor the remaining chain to the side of his sleeper cage on an angle. Quakers love to climb all over and play. The chain looped a bit lower between the ceiling hooks sways a bit and gives him good wing exercise as he tries to keep his balance while walking it.
Yeah he's a spoiled little brat,but I dunno..it just kept growing ya know?
But the emphasis really is maximizing available space. The chain allows me to hang toys from it as well,keeping his interest in walking it. Bar spacing is important as well as is overall construction materials. 1"bar spacing is best. Also, consider the color. His sleeper cage is white while the other is black. He stands out better in the white cage,being chartreuse and green.
Now cost is a huge factor for most of us, but used cages are readily available from garage sales to Craigslist ect.,for far less than the price of new cages..just can't believe how much some of these cages go for..unreal. The play gym,new at 99 bucks was well worth it. Just make sure that if ya go the seed catcher route that the sides also integrate into the vertical bars so that the stuff doesn't just fall into the seed catcher and fall onto the floor anyways via a gap at the bottom.
As I introduced buddy to each of his new digs,I kept his old cage nearby. He would look at the new one for a few days untill curiosity got the best of him..eventually allowing me to remove the old cage. Changes in his environment have to be slow. It took 2 weeks for him to venture up onto the chain,all be it he was still young. He loves his domain and stays there throughout the day even if I'm gone having windows light and food while the rest of the adjoining rooms are dark.
As far as the jewel thing..haha yes they are jewel thieves! He yanks on my gold chains and takes advantage of the situation especially when I have both hands in something and can't move him off ! They are opportunistic to say the least! Gym shoe laces and leather are favorites of his as are the caps I wear!
Made some cheap chew toys just by hanging old ones on his chain.
Best of luck to you and hope this helps ya out a bit. Search back on our threads to get some ideas for anything..there's some good folks on this site that have helped me out from time to time.
Cheers!

Yes he goes for my daughters leather handbag,pouncing on the opportunity the very second she leaves it unattended!
New gyms too..never will forget the time I took my new sneakers and placed them in the closet. I came back into the hallway ,where they were,and there's buddy sitting on the floor looking around...he was actually crying !!
