The Wyandottes are probably your best bet.
The hens are going to set when they decide to. You can hurry them up some by leaving eggs in the nest. After she has been setting for several days you should be able to move her.
I use a combination thermometer/hygrometer from Wal-Mart. They are about $10. The thermometers are not real accurate but the humidity reading is pretty close.They are digital and easy for old men to read.
