I wouldn't call it solved but at least I know I've tried every possible thing I could. I know it sounds like it but I swear I don't abuse my peacocks haha..... Just extrodinarily bad luck and maybe God telling me to pick a new hobby
Not saying you're abusing your peafowl. Accidents happen, some things you can try to treat or prevent and sometimes that's not enough. You have live birds and dead birds it's a part of life.
