one of my rats had 14 babies Thursday the 12 at midnight. I took 2 out for feeding my ball pythons and I came back in today to check in on them and 3 are died!!! I dont think she is feeding them. I took a couple and put them in with a another female rat the has done well with babies before to see if she with take them in...

What should I do?
Keep the babies with the mom.
Or give them all to the other female rat??

What are the chances they will survive?
