I raise my own mice to feed to the ferrets. The colony isn't self sufficient yet- well not enough to actually FEED six ferrets; just gives them a good treat once or twice a week. But maybe in a couple months that will turn around. Just had almost 40 pups born so far this month and more does due to whelp this week!
I've tried setting out live traps for mice in the barn, but so far, the barn mice are too smart. The live traps I set in the house to catch the escaped mice, well the domestic mice are very willing to walk into the trap!
Mice are very nutritious for ferrets!
Cheers,
Kim
