feeding multiple mice?

I have a black pastel that has grown increasingly picky. First she ate f/t although not reliably. Then she absolutely would not touch anything but live and now it has to be live mice apparently. I gave up fighting it and have fed her as many as three in one day with no issues.

Thanks everyone for the responses but really only 1 person gave me an answer to the question... lol How does everyone do it? What is everyone's method?

i use to multi feed my snakes when they before i was advised to give bigger prey from there breeder. but got a bigger burm that i still multi feed only cause i aint going to spend 20 bucks on a pet shop rabbit every week and no sense to breed rabbits just for 1 burm

they are were neos (now almost a year old green tree pythons) and around the same age blood python) but when i switched to larger prey i noticed an increase in shedding also was every couple months now since switching to larger prey they are shedding monthly and packing on allot more weight

thing I've done for my blood python when the pet shop aint got the size of rat she needs is give her a pregnant female mouse tons more for her to digest

i prekill all food unless it's a pinky or chubby (smack in the back of the head

I feed live mice to my small collection. I toss in one mouse, wait about 5 or 6 minutes, make sure they've killed and eaten the first one and toss in the second mouse. no stress, no issues. If anyone refuses their second mouse I take it out and either put it into a holding bin until next feeding day or feed if off to any of my females. Hope that helps you.
