Nothing good ever come out of being in a rush.
First you need to keep those animals in QT from your collection or other animals (2 to 3 months), if you do not have any other animals you still need to assess those animals.
Many older animals when changing environment will stop eating all together.
Breeding is about PATIENCE
As for not wanting to QT because they come from trusted source I would encourage you to think again, I don't care who the animals come from, I only buy or do breeder loan from/with trusted source myself and I still QT for 3 months, why because I value my animals and have too much invested to risk to lose it all.
