I have adopted our neighbor's hen. They put down their small flock in 2/06 and she was the last to go. When they opened the door, she fled and has been on her own every since. She has taken to my yard, eats under the birdfeeders and is currently roosting in my garage. No one knows how old she is but last spring she laid eggs for about a month. She is at it again this spring but the last several days she has taken to sitting in the hay box and only getting out to lay gigantic poop balls. I don't know how long chickens live to and could use some insight because I am worried about her apparent constipation problem. I'm telling you those poop balls are larger than her small eggs.
