Ok, here is a short story of my setup, built a 12 tub rat rack.



Set up (2) tubs with 1.2 adult rats, and another one with .4 females for replacements in a few months, I dont know how old my current females are.

Here is my problem, I THOUGHT I read somewhere that I can leave the 1.2 rats in the tub, they breed, birth, raise their litter, then wean the ones that dont get fed off into their own adolescent male and female tubs. Well, I came home today and saw some blood in one of the tubs, and saw 2 pinkies, the male was eating one and one of the females was eatin the other. I start doing more research and find conflicting advice, take the male out, ...

One of my females in the other tub is about to pop so I took the male out of there and put them in the same tub, because rats need to be kept together from what I have read, keeping one in a tub is bad for them. Well, the two males were fighting for 20 minutes. I thought they might settle it and see who the dominate one was, but I seperated them because I dont want TWO dead males. So do I need a seperate tub for EVERY breeding male I have??? Please help, I know there are lots of things here, but I dont want to lose another litter or any other rats!!! Thanks
