I don't know what is wrong with my hens though but they are not laying anymore! About last week they got sick and two died but I medicated them and they are all fine. I have two breeds of chicken that are my layers. One is the Lohman Browns and the other are chicken mutts. I give them four ounces of feed (per hen) everyday and one day every week they go into the roosters pen. The Lohmans are over 21 weeks old and the chicken mutts are 6 months old.
