Over two years ago, this hen disappeared. She's a beautiful Aracauna. The neighbors had raised four. Two disappeared and one was killed. Then another neighbor complained about their remaining hen who had become friends with our guinea hen, so they gave their last hen to us. That last hen has been confined in an enclosure with our two guinea hens ever since. Today, one of the other hens came home. The neighbors moved last month. She's this huge bird, gorgeous and very distinctive looking. I found her in our six foot fenced dog yard when I went to let out the dogs - good thing I saw her first! She's completely wild but hung out with our birds all day. They drove her off a couple of times but she came back. What would you do? Try to keep her, quarantine her, just let her do her thing? I've never experienced this kind of thing before. She was hand raised but is having nothing to do with humans at the moment.
