DNS doesn't actually 'failover'.  Both servers should answer the same 
number of queries, assuming there are no server outages to offset this.  If 
your servers are set up correctly and the root servers have the proper glue 
records for your zone, you should see queries to both servers all the 
time.  If one server is answering direct queries but does not seem to 
answer them when digging down from the root servers, then you need to 
verify that the root servers have valid data.  A useful website for running 
DNS tests is http://www.dnsstuff.com.
