Broodlord

If another permanent enters the battlefield as a copy of a creature with Ravenous, it will not enter with any counters from the ravenous ability.

You choose how many targets Broodlord's triggered ability has and how the counters are distributed as you put the ability onto the stack. Each target must receive at least one counter.

A creature with ravenous gets its counters as it enters the battlefield. It doesn't enter the battlefield first and then get its counters. Any triggered ability that looks for a creature with a certain power or toughness entering the battlefield will see the counters when it checks to see if it should trigger.
