Part of the reason for the lack of common knowledge regarding the roosters calcium trap is the bulk of the research that has gone into chicken nutrition has centered around the hen and egg laying.
The poor old rooster if wanted for reproduction got replaced by a younger one around two years old I have read.
Most roosters weren’t allowed to live long enough for long term diet problems to be an issue. I have read, that it was game fowl breeders who were more interested in rooster longevity and hence nutritional analysis.
I became interested because roosters here were dying much earlier that the hens born from the same clutch. The symptoms were virtually identical between these roosters. I started to look more carefully at not just what they eat, but how they eat which changes with the egg laying cycles of the hens.
