My flock is 13 weeks old. Right now they are on chick starter food. When should I switch over to layer food? If I remember right 19-20weeks is about the usual time frame for most hens to start laying. I figure my RIRs will follow that time line but my EEs will probably take longer from what I have heard. We don't go through food quickly and I wanted to know if when we buy food in about a month if we should buy the layer and go ahead and get them started on that.
