What age would a sumatra cockerel become sterile at, because I have a sumatra cockerel who must be about 4 or 5.and the last two hatches from him and a hen about 3 or 4 years old was terrible. Granted the eggs were travelled to a friends house for hatching and it was blackberry season, but I would of expected a better hatch rate.out of 10 eggs I got 1 and from another 8 eggs I got 3 chicks. Would it be my bad timing or would age be the problem?
