I'm getting soon in the post a hovabator as my new female hermann lays eggs - previous owner never incubated but I would like to be prepared so incubator is on the way. Can someone please advise how I should set it up once eggs do appear. Should i put eggs in vermiculite and in some sort of tub with lid then put in hova? And is a tray of water required? I've read up on others using a hova but mostly for lizards etc so need some advice for my torts. Thank you and hopefully I'll have lots of time to practise with it before she springs eggs on me!! Also will I need to buy a hygrometer or does it come with one?
