I got an old crested Pekin from some friends a while back. She doesn't lay any more and is approx. 6 yrs old.She is very sweet, but has huge cancerous growths on her feet. It doesn't seem easy for her to walk. Normally only my buff male is willing to stay and walk with her while the others speed ahead.I don't want to cull her. I'm just wondering, does anyone know how long she will live?
