I have a rooster that's proud and stands tall...very healthy. He has 12 hens all to himself. I bought all hens plus one rooster all at the same time as one day old chick's from the feed mill...in which they got them from a hatchery. My hens and rooster are 1 year old now....all of them are producing eggs on a daily basis. The rooster mates with them...I have see this. I assumed that if I have a rooster that mates that it would in turn produce fertil eggs. Meaning that I would be able to hatch my own chick's . But ..... someone told me that if the comb of my rooster is straight....he will not produce fertil eggs ...they told me that some hatcheries do something to the rooster as a baby to make them unable to fertile eggs as they are older.
