My hens are almost all quite plump, especially the barred rocks--they're enormous, and they're not laying. Out of 14 laying hens, I'm getting maybe 1 egg/day. So, today, one poor hen had a run-in with a dog, so I butchered her. She did not have ANY egg production going on internally, just a huge glob of fat on her low belly. All else looked just like the rooster I've butchered in the past. So, not laying because she's fat?
