Rather than just hand them out "free to good home" I'd say it would be far better to contact a local rescue (I will pm you their number) and ask if they can help first. Pawz For Thought are in your area and a great rescue. If they can help, they will, but like all rescues they are so often inundated with unwanted animals
If they are unable to take the mice, ask if they can recommend a rescue who can. Another option is call your vet and ask if they can suggest someone who can help.
If a rescue can take them, please ask if they want the cages too, chances are they will already have enough, but it's only fair to offer.
Please try a rescue first, so many animals offered "free to good home" end up being taken on impulse and end up in anything but. Mice are especially vulnerable as if just given away can end up as reptile food
