I recently purchased 5 sapphire gem Oliver egger chicks from a local hardware store. They carry “ pullets only “ from Hoover Hatchery. As I don’t know anything about these chicks breeding or what to expect, I emailed Hoover. They all look a little different color wise and I was told that they are auto sex so they were all female. Hoover told me that they are auto sex but that is not how they sex their chicks. I also asked what the cross breeds are and they said they can not disclose that. They are about 5/ 6 wks now and one is created and is a lighter gray. One of them appears to have slate legs. Does anyone have any of there chickens from Hoover and can give me any info?
