All thru the winter my hens were laying well. I was getting about 3 dz a week out of about 8 hens. These past couple of weeks, the eggs have dropped to a little over a1 dz a week. Now, the differences: Two of our four roosters were sold and one hen has been quarentined for illness. None of the others appear sick. One hen has been broody and sitting on her golf ball for a month and now has an egg. Another hen went broody and is sitting on an egg also. Any ideas?
