After a year of no eggs with 10 girls, I found a layer feed that was 22%. Feed store guaranteed egg laying with this feed. I am also added layer mash. Could this be causing havoc in the reproductive system? Is it too much? After 3 months I am having egg yolk peritonitis and egg binding issues. Lost one already and have another one in solitary. Very concerned. I have read that some birds just have it, like it is hereditary. Thanks for thoughts.
