At first I could not figure out why we where having such a hard time with these guys... and then it hit me. They were all going on the same init roll! They could super-cordinate their attacks in a way that we were having a hard time doing because of our random init order.
I definately see this as a problem. If all monsters (or a large enough group) act together, and get the jump on the PCs, it could turn it into a one round TPK. OTOH if you have a single roll for a group you could end up with them all acting last in a round which might be end of combat right there.
If I had 20 monsters of the same type I would probably break them into groups of 4 or 5. What I might do in that case is use dice to indicate each group, for instance using 4 red D6s for one group, 4 black D6s for another, with the face up number on each dice to indicate number of that creature.
But most of the time I give a roll to each. For example on the weekend I was running a fight with 8 small critters. I put down 4 red D6 and 4 black D6, each numbered 1-4. Then I picked up 4 D20, and declared the roll order (red, white, blue, black), and used that to set the initiative for each. I use init cards, with number barriers (index cards in a card box, I use a set of dividers I found which are for a calander month, and that indicates the initiative value). By rolling the D20s that way I didn't end up with number 1 is first, 2 second, in initiative, which I don't like (because you have placed them in such a way that those ones going first are in a better position to go earlier, for example).
If the creatures are supposed to be randomly spread throughout an area (if they are unaware of the PCs, for example), then I like to roll the dice onto the map to show where they are.
I like Mike Mearl's suggestion of taking 10 for initiative - Mike, if you try it out, let us know how it goes.
I would hate to play in a game where all monsters in a fight rolled a single dice for initiative - far too high a chance of having them all go before the PCs.
