why no-query? You should use no-query only for proxies that don't support
ICP/HTCP.

the proxy-only is OK, but no-query is bad idea.
I have 3 parents too:

cache_peer proxy1.nextra.sk parent 3128 3130 proxy-only
cache_peer proxy2.nextra.sk parent 3128 3130 proxy-only
cache_peer proxy3.nextra.sk parent 3128 3130 proxy-only

and logs show this:

tux squid # grep /proxy1.nextra.sk access.log | wc -l
197122
tux squid # grep /proxy2.nextra.sk access.log | wc -l
188456
tux squid # grep /proxy3.nextra.sk access.log | wc -l
179851

looking at cache_peer docs:

# use 'round-robin' to define a set of parents which
# should be used in a round-robin fashion in the
# absence of any ICP queries.

I think that either enabling HTCP/ICP or adding round-robin would help you.
