So, our hens have been laying just 1 or 2 eggs/day for a full week after a sharp drop-off in laying that I initially thought was feed-related. But then I wondered since an immediate switch to different feed did not fix the problem. Yesterday and today they laid 3-4 eggs/day. Not much change in weather or other conditions, so maybe it was indeed bad feed that took them a week to get over...? Or took a week to adjust to new feed...? Next step: when they are consistently laying 3 or more eggs/day, I plan to put them back on the suspect feed and see if their egg laying drops off again. Any other suggestions for adding control to this experiment and not overstressing our birds?
