I have 50 Coturnix eggs set to hatch next Friday/Sat. I am planning on keeping them inside in the basement brooder for the first few weeks (like the chickens are right now). I am just wondering how old they have to be to move them to the outdoor coup. Although we had our first snow of the year here (only like 3-4 inches) the coop is still at 48 degrees in this 28 degree weather! And that is with no additional heat, or insulation or straw!! But how old do the coturnix have to be to be moved out to the shed? When do they full feather out?
