We currently have one rooster and six hens and we get three eggs nearly every day. So, we have two that aren't laying. They're the same age, and seem healthy. We've caught Big Rose, Meatball and Fast Ted in the nesting boxes (can you tell my kids named them?? ) but nothing from Fluffy or Young Elvis (okay, I named her ). Is this type of thing normal? Could these other two be roosters?
