Hi! 7 weeks ago we bought 4 pullets from Tractor Supply, and 2 pullets from Family Farm and Feed. One of our TSC Leghorns is absolutely a cockerl, and it now appears that Our black Jersey Giant from Family Farm and Feed is also a little cockerl. Ill post pic of both. But I was wondering if Hoover Hatchery also supplied Family Farm and Feed, as they offer a 90% sexing guarantee, we have 6 chicks, and now 2 are rooster, that doesn't doesn't sound like 90% to me!
