What I've got going on is my hens just stopped laying eggs. I have ten beautiful healthy ladies, and over the last 21/2 months my egg production has gone from 6-8 per day to 1 a day. They eat twice a day 16%crumbles in the morning and scratch in the early afternoon plus what they eat while ranging on our 21/2 acres. I have a variety of breeds and a great rooster to protect them and keep them in line. They live in a barn, dirt floor, cleaned regularly, always have plenty of water. I'm totally lost, and any comments or help would be greatly appreciated.
