I am not sure how fertile Jasper is. Last year he had good fertility. I didn't put many of his eggs in last hatch but I think it was not so good. We will see with this hatch.I do not like a mean rooster ,can cause trouble to you or your man , he did manage to give you nice progeny ,so he can go .
keep Jasper fit ,don t over work him ,when you finish incubating ,you need to separate him from the hens ,so he can stay fit and healthy ,
