First time incubating eggs. They were from my "purebred" gcm and some black sex links I bought. I think I messed the hatch rate by leaving egg shells and a wiley chick in the incubator to long. He knocked over other eggs that had pips. I also probably ran on the lower side of the temperature scale. Humidity was right on the money the whole 21 days. Here are the successful hatches. One seems more brown than the other two.
