Well my babies are all grown up, and have been released back into the barn (shoosh don't tell my boss!) lol
I decided that since they are wild mice, they deserve to be wild mice, and since they have been eating grain from the barn, they will know what to eat.
Just keep an eye out for them, because im sure if your BO see's them she will kill them.Since you have raised them since little babies they may not know how to servive in the wild. And think about the cats that could catch them....
This is a working barn. There are no cats, and we don't kill the mice. I have only raised them since thet were a week old, and they have been doing fine on their own now. So basically they will be perfectly fine :)
