Mind your $ORIGIN and check the number of NS record owners.

I suspect that deltas; add / change / delete, will likely be outside of 
the scope of what bind will provide unless you crank up logging and 
parse it or behave as an incremental zone transfer client.

Mind your $ORIGIN and check the number of DS record owners.

How are you getting your zone data?  Is it a zone transfer (AXFR / 
IXFR)?  Or do you have raw zone files?

Check out the "-clean" flag to the "sync" command for rndc.

It sounds like you might be better off extracting data for multiple 
zones / (sub)domains therein from DNS and storing it in some format, 
likely a database, that will then be easier to process.
