Hi J,

I'm coming a little late to the party on this one and I think you might struggle to do rotation based on both date/time *and* file size, but I use logrotate to rotate all of my BIND logs daily, keeping 31 days of logs. And you'll see that one of the last things that logrotate does is to call [rndc reconfig] which causes BIND to generate fresh log files in place of the rotated ones.

My BIND logging itself is setup based largely on the configuration described here:
https://kb.isc.org/docs/aa-01526

My logrotate.conf file then looks like this the following, which itself is based on this:
https://ixnfo.com/en/logrotate-bind9.html

#-----------------------------------------
# RTAN BIND 9 daily log rotation
#
# Note that the log file won't rotate until at least one day AFTER you set this for the first time.
# Eg if you create this file on a Wednesday then they won't rotate for the first time until THURSDAY night:
