Hopefully the post title is not too confusing. We are new to chickens, in fact this is our first post. Anywho 4 weeks ago we received 10, 1 week old black astrolops. They are doing fantastic. From what we can tell in the group there is not a rooster. We purchased a 3 month old black astrolop rooster and a hen from someone local. We thought it would be good to have a rooster for protection for the hens. What we didnt' realize is now in the future this rooster may fertilize some of the eggs. We really are not wanting to get into the chick hatching side of things, although it may happen. how can we tell if eggs are being fertilized, or is there any way we can prevent the rooster from fertilizing eggs? Lastly do we really need a rooster around to help protect the hens?
