We have a BEAUTIFUL Americauna rooster. He's a nice guy, too -- pretty calm, reasonably friendly...you know: the kind of guy you'd be proud to bring home to mom. But we don't want (noticeably) fertilized eggs, and this boy really likes to love the ladies. We sell eggs, and don't want to worry that there will be blood spots or (God forbid) embryos inside to scare our customers. But we also really love our little rapist rooster. Question: assuming our eggs are fertilized (because Roo hops on each lady multiple times each day), are they okay for selling? Will they contain blood spots? (We've never seen any blood when we use the eggs ourselves, and we never see them when we candle, but sometimes I think it's hard to know for sure). How do I know? Do the hens need to sit on the eggs in order to incubate them (particularly in the cold MN winters)? How does incubation change in the heat of summer? (ie., if we keep rooster, will our summer eggs be more prone to blood spots?) We gather eggs daily. Even if they're gathered immediately after they're laid, is it possible to determine whether they're fertilized? I feel like i'm asking a million different questions in a million unorganized ways -- sorry! Basically, just looking for good info on how to keep a rooster without worrying about issues in egg sales... Can you help please?
