hey guys i really need some help,

I am kinda stuck atm,

it started a few months ago when my OG female decided to stop eating i was like ok, you know it is a bp so don't worry, at the time she was around 750 grams and feeding on live rats.
after a few months of trying to feed her every week and see her as if she was afraid of the rat i decided to try a mouse and she slammed it, at first i was happy ofcourse but now i am stuck with a +/-1000 gram bp that only eats live mice....

then (now a few weeks ago) my Piebald lady who is +-/ 450 grams also decided to stop eating, she was on f/t mice and now only seems to want live mice.

and as if that wasnt enough to put me off now my Pastel het Piebald lady who was 751 grams stopped eating also and now in 2 weeks has already lost 23 grams and i have tried everything today,

f/t rats (wich she was feeding on before), live rat, f/t mouse and live mouse and she didnt want anything, and my Genetic Stripe Pastel who was in shed last week (i dont feed them when they are in shed) also didnt eat today.

now i am really comming to the point in wich i dont feel happy with my bp's anymore, every week there seems to be something else the matter and i am wasting money by throwing away rats/mice after thawing them leading me to thinking about stopping with the hobby and selling my bp's.

Thing is, if it where all snakes around the 1000 gram i wound't be so upset cause then i know it probably was just that 1000 gram wall every1 talks about but they are all way lighter then that/ where lighter then that when they started with their feeding problems... and to be honest I just dont know what to day at this moment.

Feeding day used to be my favourite day of the week and now it is starting to be the day i hate the most.

any advise/ idea's on if i should indeed stop the hobby sell the animals or keep trying would be appreciated
