Huzzah! After taking a couple of months off, my three hybrid layers have begun laying again!! The Delawares and Black Sex Links kept right on laying through the winter. Now, instead of 4 or 5 eggs a day I am back to getting 7 or 8 which means I can go back to selling some to pay for feed. Here's a question though: I can tell (by color and texture) which eggs are from the three hybrids, who are nearly two years old. The Dellies and BSLs are not a year old yet. I notice that the eggs from the hybrids are very thin shelled. Is it possible that since they were not laying for two months they didn't eat any calcium? The hens all get layer crumbles plus oyster shell free choice in a separate hopper. Anyone else seen this?
