white mould, fur on newly chopped kindling stored inside

Agreed.  I think you would be better off putting it on a pallet outside with something to keep the worst of the rain off.  If it is fresh felled then it will be very wet already so not going to get worse outside and cold temps + air flow should prevent that mould. Just stack it with air gaps as you need the air flow to dry it.
