If it says
"layer", that's too much calcium for the long term health of your roosters. 3.8% on average, in the case of the Nutrena Layer.
No guarantees, of course - its like smoking. No can can stare at a cigarette, and say "that's the one that will give you cancer". But we can say that the more often you smoke, and the longer you smoke, the better your chances of developing various cancers. (and then you may still die for completely unrelated reasons).
Same with roosters and high calcium diets. Maybe its a risk you are willing to take, in your management situation. Its all risk management and balancing trade offs.
