I have 10 gold sex link pullets which have wintered over quite well. But for the last 2 weeks they are driving me nuts. I am only getting 6-8 eggs per day. On Saturday I added a pan of oyster shell calcium, thinking that would return the lay rate. Yesterday I got 9 eggs and my hopes revived. Today, I only have 5. These hens are right at one year old. They aren't losing feathers, so it can't be molt. Help!
