I had a shipment of eggs delivered to me Sat. I noticed that one of the eggs is completely oval shaped. I examined it and couldn't notice a difference in what end was larger, so I just put it in the incubator. After reading, I have seen that those ones should be thrown away, then I saw that an oval egg meant it was a male? also that they were infertile? I am new to this, my first hatch so Im confused once again. It seems like I am always searching for answers that never end... I don't want it to blow up like people said either. If I wait 7 days, I should be able to tell if there is something in there right? I am hatching silkie eggs, so they are not really dark in color. Thanks!!!
