We have 9 hens, and at least 6 are laying. They are 25 weeks old. We had been getting 5-6 eggs a day... And in the last week we have only been getting 4. I did notice that we has a shell less egg (messy!) in one of the nesting boxes, and a soft shell on our front porch. (2 different days). I am just wondering if I should be concerned about their health or am I just over thinking this... Everyone seems happy and healthy. The breeds that are laying are Barred Rocks, Rhode Island Red, Dominique, silver laced Wyandotte, and one speckled Sussex. We have 2 speckles and a salon favrolle that we are unsure of their laying progress... Any advice please!
