I don’t have to read, I know from experience. A chicken won’t lay more than 1 egg a day…that’s peak production. My current batch are going on 3 years and give as much now as they did at 6-8 months. I expect this to keep going till, as usual, 5 yrs…then it will taper off. That’s when I introduced them to the back 60. Be free little chicken! Let nature take its course. So if you have 25 chickens, you should be getting around 20-25 a day. That’s peak. If you have 10, you should be around 8-10 a day. I’m down to 6 currently and I get 5-6 a day. I don’t like introducing new chicks with older hens of I don’t have to. It gets brutal sometimes. But if I lose anymore, may have to. Of course these numbers are outside of molting and any situations where they get freaked out.
