Adding a second male to the flock is certainly something to think about.
It really depends on your set up, how you manage your birds and the personality of the birds in question.
I have a young cockerel growing up in the flock with 14 pullets, 10 hens, one rooster and now the three chicks. His hormones have yet to kick in. We'll have to see what the rooster thinks about it when that happens. I have several hens that will be delighted to tune him up should he get rough and rowdy with the pullets or other hens. It will be getting quite interesting around here in a few weeks.
