10 weeks ago I bought 12 pullets. To my inexperienced eyes they all looked the same age. The birds are kept together and fed a laying grain. We got two eggs a day for the first three weeks, then three eggs a day for the next three weeks and now for the last four weeks 4 to 5 eggs a day have been collected. So it seems only about 6 of the twelve birds are producing. My question is: should I have separated the layers from the non-layers and fed the non-layers a grain more appropriate for them?
