help!!!!

Yesterday I adopted 2 chins - 1 grey and 1 biege - from someone who badly wanted them no more. He said they're above 2 years old. They seemed active and agile but so skinny they were - 425g each - that both could escape through my 3 tiers cat cage, luckily they only escaped to jump onto my lap. I then emptied one of my ferret's cage and shifted the chins there - empty means no ferrets inside but all the ferret's accessories are still there.

Today, I bought them 1/2kg timothy hay, 5lb Oxbow Essentials Chinchilla Deluxe pellets, 12" sanko wheel, LivingWorld Fresh'nComfy Bedding, LivingWorld bathhouse and 1.5kg of SankoWild bathing sand from Pet Safari Ikano. This evening, both chins took some 1/2 hour investigating the bath house before taking their dustbath. However neither of them are using the wheel.

My questions;
1. Do I need to apply for a license to keep them? If yes, then please elaborate the procedure.
2. What is the ideal weight for a 2 years chin? I heard somewhere that different colour chins have different ideal weight, is it true?
3. How do I tell a male from a female? Both chins are of equal size and weight and their genitals looks the same though, and the guy I had them from also haven't got a clue of their gender but he once "had a baby" from these two - that's as far as I was told.
4. Is a ferret's cage setup suitable for chins? Do they do well on hanging hammock or tunnel?
5. Did I buy the right kinds of food? And how much food does a chin need a day? Do I serve the food several times a day/night or do I just leave your suggested ammount in the cage everyday?
6. Does a chin really use a wheel? These two are not interested with the wheel at all - much like my ferrets.
7. When again can I give them a dustbath - that they've already had their bath this evening.

I really am in need of answers right now and I would appreciate any informative answers from you guys. Thank you in advance.

I really hope for everyone in chinchilla tread to be reasonable and constructive.

For anybody trying to say " If you don't know all this, why would you had them the first place!" , be known that my answer is "Does saying that solve any problems? How would such sentence give me any help, now that I've had them anyway! " - Just making myself clear hahaha.

And my ferrets, many a times today have they collectively tried to earn themselves a new kind of meal, but it's not that serious as chins can hop and ferrets only crawl and climb.

Thanks again everyone.

Today i finally sexed my two chins hahaha... all this while, i thought both of them are males, as i was looking for the wrong place n the wrong organ... i was looking for a vertical slitbelow the vents' fold like would my rabbits. Thanks to the many websites i researched, i finally got to know that a chin's slit is horizontal n located exactly at the fold...
even that its been almost 2 weeks now both chins never used their wheel, so i moved the wheel into my sg's cage n they seem to love it.
i first bought them a totoro house but it cannot fit 2 chins, so i bought another one n place them side by side,
can anybody here teach me how to post a picture please... i'd love to share their pic with everyone, u see here, i'm a chin nubie n would love to here any useful comment from u guys...

Thanks rjb123, so someone has answered my questions at last...
I'll do away with the hammocks n wheel, but what happen now is that my chins has managed to escape from their cage again, they look big enough to not escape, but after a few days they easily slip through the metal bars of the cage...
So they are now in a standard 3 feet rabbit cage... i'll try to upload their pic once i find the "Add this attachment" button...
About ur chin, hope u find him a good home

Thanks jcloh, so now i'm testing my first pic post...

If there are anything that is not right, please inform me, i tried buying almost everything that spells chinchilla on the tag, only to find out that some are not good for them - like hammock n wheel...
