6 weeks ago our family dog attacked one of our barred rock hens. We nursed her back to health & her feathers have almost all come back in. She has a bit of a limp still, she's eating & drinking well. Her comb is still pale. She has not laid an egg since she was injured. Is there anything I need to do or just let her be? Will she lay again? They are only 8 months old & she is one of 5 hens that we have. Thank you
