My friend recently consulted me about her chickens not laying. I offered about 10 different reasons why the wouldn't be, mites/lice, worms, molting and lack of light included. She says those aren't it. She said that they stopped laying right after the day the farmer next to them spraying his fields and a strong wind blew the chemicals all over their property and killed most of their garden. Is there a connection between this and the drop in egg laying? They haven't been laying for about 3-4 months. I asked her how old they are, still waiting for a reply.
