I have 52 chickens and since June 1 they have dropped their egg production down to either 5 to 11 a day. It is October 21 and they are still doing it. There are feathers everywhere. I am not for sure what happen to them. Can food do this? Our store had a sale on 18% feed and I bought a whole bunch and it seems like since I did this they went into molting mode. I have since raise it to 22% egg producting supplement and still the same. Please help me. Can it take 4 months to molt?
