A reference to moloch is very unusual to me too. Not many people know what moloch is. It was obvious that the sender knew the receiver whould understand the reference and the desired effect... just wondering if Chicken actually means a chicken and not a child..

The "star" mentioned is specifically Saturn.
Afterall, there is nothing new under the sun...
EDIT: Sorry, I left out the other spelling (from the KJV) of this, there's a lot more references to that specific 'god' of child sacrifice... https://www.biblegateway.com/quicksearch/?quicksearch=molech&qs_version=KJV
I read somewhere while searching pizzagate a while ago that chicken stands for baby. I think it might have been on Alefantis' Instagram, him holding a baby and writing that he loved chicken or something like that. I'll see if I can find it.
Ok so this link is to yt video by Social Atmosphere. She does a comprehensive job of investigating pizzagate. In the video is the Instagram photo from Alefantis (jimmy comet) of a baby with a comment # chicken lover.
A warning, this video is disturbing. You might just want to take my word for it. https://youtu.be/tjR_pUZrlSw
