Yep, it may be age. Although Chickens can live for as long as seven years, they only lay eggs for two or three. If you don't have space for a retirement pen, its time for the choppy chop.
If its not age, there are several things that will keep chickens from laying eggs. Stress, major changes like relocation. Not enough light (egg laying is seasonal) or they may have inadvertently saw a Jane Fonda movie. Make sure you have the basics right. Food, light, shade, a safe hide, enough space per chicken, Mel Torme music. Then go from there.
