thanks for your input! my chickens have been laying for a while now, and the rooster lives with then, so i am hoping to incubate them. i am going to try and just make my own. using my own directions, and if this does not work, i'll go for the stryfoam incubator, and if that doesn't work. i'll buy one, i'm just really interested in finding out what works and what doesn't. so the rooster lives with the two hens all the time. so is there any chance that any of the eggs arent fertilized or not? and how long does it take for an egg to die, she doesnt lay on them, so like how many hours would the egg not beable to hatch?
