I have a female that dropped 12 babies two weeks ago. They are just entering their hopper stage. Well now its 11 since we have one baby to the corn snake.

My question is, what size tank should I house her in while she nurses these 11 babies up until weaning age? Also, she's showing signs of a second pregnancy and I suspect her to be in her second week as with her first litter, she started getting large in the second week and really ballooned out the third week. Will it be ok for her to have her second litter around the same time the current litter is hitting 3 weeks?
