Along with the links, breeding season can be reduced by cutting light times.
Another issue may be that his health was iffy when you got him, he got on a good healthy diet and these are his true colors. Or perhaps the reverse and there is a health issue.
Has anything changed in his environment? Has your caging changed, the room changed, a new animal entering the group (even caged apart)?
While the issues are likely breeding season, these are other options. Breeding season isnt fun at all for males.
