I had a nice, well thought out, long explanation post typed up, but my computer froze and I lost it, so here's the boiled down version:
Cait's Critters: chickens cheer "hooray" in baby voice from Children of Morrowind.
Followed abot's advice and checked my mods for sound gens without assigned creatures. Found one each in four mods and deleted them in EE. Chickens still cheering.

Merged and customized (not in list):
LCV, NoM 3, Animated Containers, Animated Morrowind, a custom startup mod, a custom Witcher race mod, a custom Balrog race mod, Dwarves mod, Lothlorien Elves, Telperion and Basemant, Raven's Armor, and Melchior Dahrk's Grazelands Mallorn Forest.
Due to the heavy customizations and merged mods, I use MLOX as a guide and never allow any program to auto-fix anything.
Any ideas? After deleting the blank soundgen entries, I'm at a loss. It's nice to have a cheering squad, especially for a new character right off the boat, but I have the feeling it's going to get annoying.
