does a rooster ever lose his fertility?

Yes they can lose their fertility. Age? Depends; like in humans one man is infertile at 30 and another can still reproduce at 65.

They (cocks) can also come in and out of fertility during the year.
 
Though cocks as young as 3 should be fine there could still be a problem with this particular cock: injury, too much fat, genetic, etc.

You will also see cocks that are not as fertile during the hottest days of summer/ coldest in winter and, of course, during the moult.
 
It only took mine one day in the freezer…

Best average age? Now who wants anything that is average???????? lol. Personally, I like to use cocks that are under 6 years of age.

The secret is to always have youth on one side of the breeding equation: cock x pullet or stag x hen. Breeding an old hen with an old cock gives very poor results. Sometimes you may have to do it, but it is best if avoided.
