RIR have been bred to be good layers, not good broodies - you will need to get a "broody" type of hen for this purpose (who probably won't be a prolific layer

) Though there are some good dual purpose breeds out there.
If you are going to hatch your own hen's eggs, you will need a cockeral to fertilise them - though he may need more than 3 girls to keep him amused (& them with any feathers

) & a "broody" or an incubator.
You don't need a cockeral about for a hen to go broody - it's a natural thing (unless it's been bred out) for most hens to do.
Try looking in your local farming/smallholding ads or locate breeders online. You may be able to pick-up the occassional "broody" at a poultry/livestock sale - though they usually have chicks with them (be careful - they may not be as they seem)
& may not go broody again this season.
Good luck
