it takes a little while for chao to get older but you have to care for it and after a while(depending on which character you use hero or evil)then the chao will go to the stage of chao death.
If you treat your chao nicely he can live up to 8 years
It takes about 3-5 hours for a chao to reincarnate, so it would take 6-10 hours for it to reincarnate twice. This is taken from the game Sonic Adventure 2 Battle.
There is one in the 3rd chao box you break in City Escape, the 3rd bow in Dry Oasis, and other places. Mystical animals are all found in the 3rd chao box. No specific order, as long as you break the third one.
is it in another garden? if so you have to go into that garden. If not, Chao take about the same time to age but maybe more, maybe less. You also have to be in the garden for it to age and it may just be its taking a long time. If this has been going on for a very long time, it may just be a glitch.
Your chao needs to be 5 years old to reincarnate you must wait in the chao garden at least an hour or more for it to turn a year old.
A year for a chao is 2-5 hours spent in the garden. Dividing that by 365 and multiplying by 3600 gets you the length of a chao's day in seconds.So a chao's day is about 20-50 seconds.

keep giving a chao green kangaroos. NOTHING ELSE. It takes a long time.
In Sonic Adventure 2 battle a chao that looks like sonic would be neutral/running/running you could give it chao fruit just as long as the skill with the highest level is running for both evolutionary cycles.
You can obtain a Gold Chao in Sonic Advance 1 and 2 by finding it in The Tiny Chao Garden, in the shop. There is a chance that there will be a Gold Chao. You can get other Jewel Chao, too. You can also transfer the Chao to Sonic Adventure 2: Battle by using the GBA link cable to the Gamecube or Wii. And also you can get one in Sonic Adventure DX but I'm not sure how...I don't own the game sorry. D: But I hope that helps!
Chao Chao can reincarnate on SA2 battle (so long as you look after them WELL). once they die, if reincarnating, the cocoon is pink, if disapearing, it will be grey. ....Meowth!
I think you already have one when you start because I've had mine for a long time so I don't remember doing anything special to get it hope it helped! : )
There is more to Sonic Chao than the first evolution. First raise your chao to have high speed until it evolves into a green adult chao (Adult Speed Type) and then keep feeding it green chaos drives and no other drives. he will slowly change into a Sonic chao. (This does take a long time to do!)
stay with your chao long time.and wait it to retincarnate..^_^
Its about 3 hours
