I was told that it was fine to feed roosters laying mash, but then I read that it can cause deleterious health effects for them, including kidney disease, because it has more calcium in it than they need? Apparently, there is no dedicated rooster feed out there. No one seems to concern themselves with the health and longevity of roosters. It's all about hens and laying. Is wild game bird feed, which doesn't contain calcium, the best food to give roosters? But how would one stop a rooster from eating the laying mash if he preferred its taste to the wild game bird feed, and how would one stop the hens from eating the no-calcium wild game bird feed, if they preferred it to their laying mash? They wouldn't necessarily eat the right food for their gender just because both types of food were offered free-choice; correct? This seems like a hard problem to solve.
