In total i have 5 rats. 4 females 1 male. My plan was to keep two females per bin and rotate the male. I put him in with females #1 and #2 and pulled him after being in there for maybe a little more than two weeks and he has been in the tub with females #3 and #4 for about two weeks. Females 1&2 dont have any signs of being pregnant and neither do females 3&4. Is it time to get a new male? All females are big enough to breed and so is the male.

Thanks for the help in advanced.
