I have 13 egg layers. They are Amber Links, Eyes are Brown and a black Sexlink. They are 6months old and some have been laying for over a month. I started with one, then two eggs a day, then a couple of days got up to five. Now the weather is cooler and my production has dropped to two a day. I feed them layer food and have even gave them in one case, red pepper. Any help would be appreciated.
