So far we love this incubator for our duck eggs all 18 are fertile and looking healthy at day 8! It comes with the candling light on top and digital display of the temperature and humidity levels. Automatic egg turner rotates eggs every 2 hours and stops the last 4 days depending on what you are hatching. Settings are so easy to set for the number of days whether you are hatching quail duck geese or chicken eggs that depends on lockdown days so truly easy and almost hands off system! Dual AB humidity trays with external water bottles make refilling easy and convenient. LTKSeasonal LTKSpringSale LTKSaleAlert
