Igot 6 buffs in Feb 2015, all seemed to go well and they produced wonderfully. Usually a egg a dayu til September. They stopped laying very much and started molting so I decided to worm them. I got a few eggs but not many. Then it rained terribly for a couple weeks and they seemed to outgrow the hen house. We built a better and dryer hen house. We are getting 1-2 eggs a day. We live in eastern nc so it is now cold. The chickens seem healthy and are eating well. Is this normal? I expected a drop in production but just not since Sept.
