i reduced my flock from 21 to 17 . on tuesday and i have seen a drop in eggs. the most i got a day when i had 21 layers was 18 a day and since i rehomed 4 older hens iv got 9 eggs wendsday and 10 eggs thursday. 14 of my layers i have now are pullets all 8-9 months old. hopefully they will start laying again. i did change feed a week ago that could be something to do with it. its the same brand i just switched to crumbles instead of layer mash it has 1& higher protien. im in maine to and in the middle of winter maybe they are just waiting for warmer weather i have a light in the coop on a timer been useing it since october.
