Yeah,
I seem to have the habit of killing threads.
I think your lil guy could be going into shed mode as you suspect.
The peach colour was kind of even and all along his belly?
No red spots or anything?
I'd make a point of peeking at him over the next 5 days or so to see if he goes blue.
I found my snakes eat on a more regular basis once I moved on to small rats rather than larger meals but even then my males are being kind of picky just now.
The big male will happily eat two mice every week but will turn his nose up at rats of any size, the lesser has refused his rat two weeks running and last night the black pastel (only 366g bless his little cotton socks ) decided he didn't want either the usual mouse or the small ASF I was trying to tempt my non-started hatchlings with.
I do have one big female with small follicles so I am hoping that her scent is the reason the lesser is being fussy. The big male was always in love with mice and occasionally finiky about rats. And I think the little black pastel is just being a spoiled little brat.
