Hi i am new to the incubating thing i usually just order day old chicks but i am wanting to incubate a few eggs so my children can learn from the process. My question is how do i go about doing it i have an incubator and turner when are they supose to go on lock down and when do you turn the turner off and take it out of the incubator. also someone told me that i can use eggs that has been in the fridge for a few days is that true
