I have been buying a feed called "faithway" brand 16% layer pellets for 3 months now, my hens aren't laying any eggs! 1 a day maybe. before i was feeding co-op brand layer pellets and they were laying just fine, it actually made them start laying the co-op brand did. then when i switched them over the other brand of feed, their egg priduction decreased to 1-2 eggs a day, and they get extra light during the day, they get 16 hrs of sunlight per day and none are sick, no egg-eaters, mo hiding the eggs, freash water always, so could it be the bad feed causung them to stop, the reason we started using it was because it's like half the price of the co-op brand of feed. any suggestions??
