My red sex-link hen, Peach, is 3 years old. A while ago I noticed that she was getting bigger, but I just thought she was gaining weight. It's been a long time, and I think she's slowly just been getting bigger. Today I went to pick her up and I had trouble because she was so heavy. I realized how large her abdomen was when I felt her bottom rub against my arm. She doesn't jump up on the perch at night, and instead sleeps in the nest box. When I go to put the girls up for the night they all come running, except for Peach, who waddles. I don't think she's in pain, but if she is I feel terrible because I haven't done anything about it. I can't remember when this started, but it's probably been up to 9 or 10 months. So what do you think, internal laying? How much do you think it might cost for surgery?
