We have four hens (2 Easter Eggers, 2 Buff Orpingtons) they will be 6 months old the middle of this month (Jan 2013). We are in Southern California. One of the Easter Eggers layed her first egg yesterday. How do we feed them? Do we need to try feed the laying hen layer feed separate from the others, or can we feed all of them layer feed since they might be close to laying? Any suggestions?
