Is there anything in your lease against pets or reptiles? If not, then you may be able to fight it.

Honestly, the only thing you can really do is look for somewhere else to live or get rid of your collection. With that big of a collection, finding somewhere else to live might not be such a bad idea. Maybe ask your landlord if it's possible to keep a few of them? At the very least, maybe ask for more time so that you can find them homes. The last two people I knew who had to give up their snakes because of this situation had to split their collection among a few of their friends' houses and sell from there.

You can hide them at someone else's house for your next inspection, but then you risk your landlord finding out and then kicking you out without a chance to fix the situation.
