Since we had the deep freeze in December (?), my egg production fell dramatically. We have 11 chickens who are about 20 months old. Until the fall molt, we got 10 to 11 eggs per day. After the freeze, we got 1 per day. That has risen slowly to 5 or 6 a day. We have tried almost everything we can think of, including adding sprouts to their diet during the winter. Some of the chickens look like they are in molt...their feathers are wild. We have no idea what we are doing wrong! Can anyone help, please?
