OK ladies and gentlemen, I have a question. Around September last year I gave a friend of mine several chicken eggs to put in his incubator. He has hatched eggs before. Well, after being in the incubator for several days he candled them and told me they were not fertile. Now, I do have a rhodie rooster. Fully mature (3 years old now). And I have seen him cover my girls. There was a brief period where the eggs were left a room temp before they were put in the incubator. Could that have hurt them in any way? And what about my roo? Could there be something wrong with him? Do roosters become incapable of doing their job after a certain point? Finally, is there anything I can do to help me for the next time I attempt to hatch my own birds?
