Well i got 20 more AFS's to start a new blood line put one of my new males into a tank with a few from my new rats and added some from my old blood line. None of them had baby's yet but one of my old blood lines was going to have a litter. When i got home from work tonight the male was beat on pretty bad i had to feed him off. Did they att the male because the female was going to have a litter ?? I have over 150 rats from my old set. This is the only one that was beating on the new male all my other are doing fine. Anybody think they beat the male because she was going to have a little from a diff male ??
