So i get home from school and i start cleaning the rat rack. I get the my colony of asfs. I pull out the tub and i see a dead bloody rat. Its the male. his back end it bloody and bitten. They have been together for over for 2 months now and all was well until now.
It seems like im having the worst start possible in starting to breed the asfs

Also do you think i will be able to reintro a new male with out the same result. Would you recommend trying it and watching them for a while or start all over with a new trio
