Interesting and something I was going to start a thread on. In 3 of my 6 colonies I have found multiple dead babies. Sometimes pinks, sometimes almost weans that have had their heads chewed off. I have never seen this in regular rats. Has anyone else had these problems? I give them a hide and I try to wean the babies as soon as possible (not sure if I'm doing that at the right time since they grow so slowly compared to reg rats). I am running 1.3 in all the colonies except one which is 1.5 (and has experienced no cannibalism).
