Everyone here is so much help, thanks for answering all my questions . . . I have another though! Got my first eggs - goin good now in my brand new Genisis 1588, glad I spent the money (I bought a batch of feed store chicks raised then to 6 weeks and sold them to pay for incubator and eggs) NOW, I have been noticing on here lately that people keep mentioning the need for an incubator and another one for hatching??? Do I need to buy two??? What are the drawbacks if I just have one???
