New to the message board and incubating. This may have been covered in a previous post. Incubating in a LG with turner and fan. Mercury thermometer reads 99....a digital thermometer/hygrometer that I placed in the incubator 2 hours ago reads roughly 5 degrees different ( lower ). Both thermometers are at roughly the same location in the incubator. Duck eggs have been incubating for about 48hrs. Which thermo should I trust? Have I lost the eggs before even really getting them started? Thank you for your help.
