Ok here is something freaky, When my Jill first had kits they where fine in there nest box but they soon started to wander. I noticed a couple had gotten out but not travelled far, i was able to pick them up put them back into the cage and i noticed another one was still missing,
When i checked my hob he had picked it up and put it in his nest box, had anyone heard of this? he was the father of them, which im sure has something to do with it
