Hi, I've had laying hens for several years. I have a young batch of 6 leghorns that started laying about a month and a half ago. It seems like I go through a lot more chicken food for this batch of layers than my previous ones, which were dual purpose. I got the leghorns so they would eat less. This month they went through a 50 lb bag of layena in 2 weeks! I used to have a bag last close to a month. In the past couple months, I've tried 3 different brands to see if that would make a difference, but so far, no luck. I live in WI, so it's cold, so maybe that's affecting them, and also, I've kept light in their coop all winter, so maybe they are eating during the night? I don't know...how much do your chickens eat?
