Black Adder

This may or may not be the best place for this, we will see
So I have an adult female Moluccan Scrub Python( amongst MANY others,lol)
Have had her approx 2 years and ever since having her she was a very fussy picky eater, sometimes devouring instantly, others needing to be left with the prey for a day or more
Tried everything, mice, rats, chicks, quail, live, ft, thumped you name it there seemed to be nothing that grabbed instant attention.
About 7 months ago she just stopped eating period, nothing would pass her mouth!
Have kept her going by blending mice up and tube feeding and yes she is doing ok( poops, has shed etc) but this is getting very tiresome and worrying
She is in same conditions as always has been and the other 60 snakes live in, have tried in a seperate area with more heat, humidity, less heat , humidity etc, nothing seems to help
ANY thoughts or suggestions or questions are welcomed at this stage!
