"Because the Hobbits never left the Shire much, so few folk knew about them.... And trees rarely travel, so I don't think the ents knew a lot that they couldn't overhear from folk wandering through the forest!"
I don't know either, but Hair's answer makes sense to me. I wonder also, even though the time of Middle Earth is long past, if the hobbits were a relatively new species, or at least relatively new to Middle Earth, and had not made their appearance there until after the Ents had pemanently settled in Fangorn.
