I don't know about age because ours are only 9-1yrs. But I started vitamins and the one chicken who hasn't layed since August started laying. Yes, light helps.Ok,
Half of my flock is almost 3 years old, the other half is almost 2. I provide light at night, feed them layer feed from the local co-op (ground corn, oats, additives, roasted soybeans, etc.) and good table scraps (friut, bread, oatmeal, etc.), they seem healthy, and they get lots of fresh air and water. Still, I am getting 5 eggs every day, out of the 18 layers we own. Do I need to provide them with more light? Do they need more light at night? My mom tells me they are getting old, but they are mostly Black Star birds that are supposed to lay for at least 3 years. They were very produceful, the first batch started laying at 20 weeks. Are they too old? 2 of them are Leghorn layers but I only get 1 white egg per day. The coop is kept pretty clean and they have plenty of room. What do any of you think is wrong? I read the article, thanks for posting it, but I still don't know. My egg customers are hoping for more eggs per week, because I used to sell 13 dozen per week, now it is down to about 4 or 5. Thanks all.
