Are your chickens old?
My brother has chickens and they don't lay like they used to, but he said that they're all old and aging out of laying.
No ... these are two years old. Not only from our experience but like I said ... it' everyone around us, all of our friends on Facebook, and the chicken groups my wife is a part of which is all around the country.
I said 2 months but my wife said they quit laying in October. We were getting like one egg every few days for 3 months. We only have 7 chickens and a rooster but typically get 4-5 a day. Typically shorter daylight can affect them for a few weeks or so but there are things to bypass that like adding artificial light to them. That didn't work this year. It wasn't until everyone changed feed and upped the "protein" that we started seeing results.
