Shaking while eating??

Hi!
So ive noticed this last week... and she’s done it today again, too. so, i got a champagne female bp and she’s about a year old. i feed her every tuesday and i’ve had her for two weeks, i got her on sunday the 6th and i know you guys say to wait a week before feeding but she seemed hungry and i fed her and my new corn snake (and obviously she took it or else i would’ve waited another week before posting this lol) and she strikes and eat her mouse but when she’s working it down, she starts like moving side to side like she’s shaking? (if that makes sense) she’s done it both times now. but it doesn’t seem to affect her eating and swallowing. i’m just wondering if it’s normal...
thank you for reading :)

Not sure what you mean by "moving side to side"? They slowly use their neck muscles to push food down to their stomach, and sometimes when they stretch their
necks out, they lack the strength to hold steady so you might see some "shaking"?...but it sounds like you mean a faster shaking, like a "head wobble" that some
are known for? A video sure would help. How many seconds does the shaking go on for? (counting "one thousand one, one thousand two..."etc)

Champagne ball pythons can have a wobble similar to spider ball pythons so that may be what you saw.

this is what she’s doing. this was from last week tho, i didn’t think about recording her this week. i’m sorry, and i’m sorry for this being upside down. but this is my champagne

It's a champagne just like spider, champagne wobble to a certain degree usually more noticeable when feeding.
