I have 18 chickens. Four are four or five years old. About five are around 3 years old, 7 are 9 months old and two are around 3. I am lucky if I get 3 or 4 eggs a day. I don't expect the oldest to lay but I should still be getting some eggs!. Another thing is I had two campaines. One died and ever since then, the other campaign has not laid at all. I know because she is the only one that lays white eggs. Any advice? No one is stressed, everything in their lives are the same, they get calcium, greens and cabbage. Would cabbage make them stop laying? Any advice would be so appreciated! Thank!!
