I made the mistake of feeding extra when winter started, thinking they'd need a little boost. Egg production dropped overnight. Then I ran out of chicken food over a weekend when I couldn't get any and I fed them a bit less than usual. Suddenly they laid like crazy, so I started experimenting... I told a farming friend what happened and it's worked for him too. The tricky bit is figuring out exactly how much to feed to get the best from them. It look me awhile.
Due to a recent outbreak of break-ins in our area we seldom leave the house for even a few hours. We got burgled twice during the day! If we have to go somewhere I ask someone to house sit and look after the chickens and feed them for me.
Had an interesting and pretty cool experience food-egg-wise this past week: I was given a whole lot of dried corn on the cob, which we've been cleaning and preparing for my chickens. It's very time consuming, but, hey, free food! I'm not complaining! I soak the corn kernels in boiling water for a few hours and then grind it up so my debeaked layers can eat it. I soak the lay pellets overnight, mix it with the ground corn and feed it to them wet in the mornings, then just the corn, wet, in the afternoons and evenings. Over the 7 days prior to us getting the whole corn I fed them cracked corn which I normally buy. I got a total of 161 eggs over that period. Since I've started feeding them the ground up corn I got 207 eggs over 7 days! 46 Extra eggs for that week... I still feed them the same amount. I feed it wet so they can pick it up with their blunt beaks and also so I minimize waste. I've been using an old fashioned meat mincer to grind it, but a food processor should do the job.
