I do think this poem is choppy, but it comes with the word hours you've made rather than the structure. The poem uses words that are mostly two syllables or shorter, until we get to the last two stanzas. This brevity is interrupted with "beguiled" first, because it is uncommon in general conversation, then harbinger, then chrysalis.
This poem appears to be about being trapped in society's standards and the eventual apathy that arises from being raised I it.
I believe it does, but it applies to your fourth question. The poem begins with the combination of two cliches "run free" "trapped in a cage" and continues into ambiguity. What double edged blade are you speaking about? What are the voices protesting and why are there deaf ears? (Two more cliches).
The second half of the poem is really the meat of it all. I believe restructuring the beginning it in your best interest. Play with new ways to express these sentiments, especially in the beginning. Starting a poem with this many cliches is an easy way to turn off readers before they get into your work.
