Our hens have yet too lay ANYTHING! I have heard 2 schools of thoughts about nest eggs, one being that they will cause the hens to begin laying, and the other that they will stop production. As we have had no "production" yet, I am thinking about trying it anyway! Our girls are Rhode Island Reds and are still pretty young - only about 28 wks (approx) old. Any thoughts or suggestions would really be appreciated!!!
