snake food is pregnant! help!

[frankadank]

so basically as the title goes... i have 3 mice which my snake is not eating right now due to shedding soon well i clean and feed them regularly and today while i was cleaning the tub i realized one mice is a female & is massive she has to pop any day now! hopefully my snake sheds and can consume her before that time comes.. but i want to prepare for i guess a litter of mice.. i’ve watched some videos and read up on it but can’t necessarily find what i need. has anyone experienced this or breeds mice that can help me out? don’t know if i should separate the pregnant one with the other 2 and if she’ll just take care of them & nourish an help them grow until it’s my turn, or do i take over when i see pups? i’m going to go up to the store i purchase them from and see if they have any advice but thought to reach out here. thanks for any input!
