Bukkit

I am using this plugin on Cauldron server, version: 1.7.10-1.1207.01.187

Everything else seem to follow the limits but for some reasons, every now and then, Chickens spawn in big amounts.

Even when I have debug-messages: true I see that Chunk Spawner Limiter is actually culling chickens. For some reason, it sometimes doesn't do that.

  ANIMAL:60
  MONSTER:100
  NPC:100
  OTHER:100
  SHEEP:3
  CHICKEN:1
  SQUID:3
  PIG:2
  COW:2

For testing purposes I set ANIMALS to 1. Looks like all animals are missing now but sometimes a group of 3-5 chickens still keep appearing (checking world generation by flying in creative mode).

PS. I noticed some error messages in Cauldron log. To satisfy Cauldron I edited configuration file "entities"-section...

#before
entities:
  ANIMAL: 100

...to look like this:

#after
foo:
  ANIMAL:
  entities.ANIMAL: 1

After the change, Cauldron log file doesn't show errors any more.

After trying JAS and realizing that chickens have rather big chance to spawn passively I guesss it's the passive spawning that causes chickens to appear.
