Someone told me that if you always let the rooster be with the hens it will cause blood in the eggs all the time. Is this true or is the person mistaken? I have read that sometimes there may be a small amount of blood in the egg which is nothing to worry about. We now have a rooster but have not put him with the girls yet. Before I do I want to be sure of this before putting him with them all or just a few. Still new at having my own chickens and still learning. Any thoughts. Thank you!
