Okay, my hens are old enough and WAY big enough, but still not laying. We have about 80 birds...about 9 of them are roosters. We were getting some eggs, however they were not laying them in the nesting boxes, but in the back of our truck instead. When we moved the eggs, they stopped laying. We have Barred rock, Rhode Island Reds, and White leghorns also some Silkies...they only ones that were laying were the Leg horns... any information would be great!! We also had a small hen and rooster (set) she layed about 7 eggs, then never layed another.
