Came upon my attention a couple of months ago about the issue with Purina layers chicken food being contaminated... I was getting two eggs a day out of my seven since September. I switched to manipro and now I get three eggs a day I also tried Kamalacha and nothing happened so I went back to manapro and I'm getting three eggs a day.. so I'm not going to buy any more Purina and go for broke with the Mano pro and hopefully the other four chickens will start to lay.
