Gnomish

porogog

noun. the clucking and noise of fowls

The word G. porogog “the clucking and noise of fowls” appeared in the Gnomish Lexicon of the 1910s as an elaboration of G. porog “fowl (domestic)” (GL/64).

Neo-Sindarin: Since I think ᴺS. porog “fowl” likely remains valid, I’d keep ᴺS. porogog as well for purposes of Neo-Sindarin.
