I'm new to breeding mice and discovered my baby mice being eatin by the adult mice in the colony. This has happened more than once now. The first time, I thought it was because I disturbed them. The second time, I thought maybe the cage needed cleaning. This time, in a quiet place - undisturbed, in a cage that was cleaned the day before the births, all the babies are gone! I removed one adult that I caught doing it, but obviously there is more than one in the colony of 6 females and 1 male.
Do I have too many in the colony? The container is a LARGE opaque plastic bin with a mesh wire top.
There is an overabundance of food and I give treats of carrots, lettuce, apples, raisins and waffles!

I'm doing something wrong here - HELP!
