How long to wait between getting new snakes?

[Gocntry]

But are they being quarantined in the same room? Cause each time another is added the clock should restart

I confused on that question..... Do you mean are the new snakes quarantined in the snake room? That is No.

I have 2 other bedrooms, I can keep a snake in, The snake room is separate from those rooms, other end of the house.

New snakes get handled / fed last if multiple snakes are being handled / fed in the same day.
