Can anyone tell me if this is any good? I am new to incubating and was going to get the little giant still air incubator but need to know if it is any good? I don't plan to hatch a lot, I don't have the room for many but I would like to see what I get from my flock. How long should I have it up and running before I add any eggs to it? My silkies have just started laying again since they stopped when we got our first snow. I have no clue how to do this and thought I would ask here.
