Chinchilla colony

I need to rehome my colony of chinchillas. There are 4 females aged 6 months to 4 1/2 years old. Two are standard dark gray, one is charcoal, and one is solid white. There's one 2 1/2 year old male and he is a light gray. They all live together in a multi-level ferret nation type cage. Three of the girls have had babies before (the 6 month old has not) and all are probably pregnant now.
They're all sweet and can be handled. None have ever bitten. The male and the young female are not thrilled with being picked up but the others don't seem to mind.
They will all eat out of your hand.
We have had them for years and truly enjoy their antics but we had to take in a family member with some medical issues and he has severe allergies to the chins. Their dust bath sends him otni an asthma attack.
Please only respond if you have chinchilla experience and are serious about adopting them as a group, cage and supplies and all. We're not splitting them up. Must be picked up in central Florida.  No shipping. 
Make a fair offer. More pics available to serious inquiries.
