I had an ISA brown hen who was my best layer of huge eggs every day. Then she was injured by my good neighbor’s dog when they were walking by. She had escaped our yard and always liked to visit other field’s and lay eggs in our old corn crib.
She looked dead, but she did eventually recover later. She immediately went into a stress molt, and did not lay again for 3 months. She always laid a soft egg from then on, almost every day. But she never seemed to feel bad like your hen seems to when one is coming. My ISA went back to roaming all over to free range all day after laying. She died within 18 months of a reproductive disorder, probably due to the injury. Hopefully your hen will get better.
