I wish Lima was a naked neck but unfortunately she is an Ex Battery Red Sex Link with problems. The back of her head is bare because Henry really like her and when mating he pulls her head feathers out.

An added problem is Lima really likes Henry and unlike the other hens, she doesn't tell him no often enough. Henry is quite happy to accept no as an answer to his advances and I've told Lima numerous times to say no and dodge him.
On the face of it one might consider my resistance to seperating her, or him, as poor husbandry but the fact is, the seperation would send Lima into immediate stress and given her heritage, stress is the one thing that is likely to decrease her already short expected life span.
Recently she has been saying no more but she's a happy little hen, super fit, alert and interested in everything around her and as long as there are no wounds as such, she is much better off with her friends than she would be isolated for the length of time it would take for her feathers to regrow.
The probability is she will die this year. She has I suspect Salpingitis which is common in battery hens and she is three years and some moths old now. Most battery hens die at around four years old so she doesn't by averages have that much longer to live. Better die happy with her friends, even if she does look a mess than in isolation, feeling miserable, lonely and stressed.
