I don't know if this will help either one of you or not, because I knew exactly what was wrong with my hen. After the 5/22/11 tornado in Joplin, there was debris all over our yard, and in our coop. I watched my hen grab up a piece of that pink styro-foamy insulation and choke it down before I could get to her. Sure enough, two days later she looked miserable, not eating, losing her color in her wattles. I spent one entire day giving her a mixture of olive oil and red wine (which she quite seemed to like after a while), first by eye-dropper, then she started drinking it herself. Then I would massage her crop for 20-30 minutes, while she and I watched TV. Well, I watched; she mostly went to sleep. I tried to gently break up what I could feel in there, because I KNEW it was the insulation. Then we'd take a break for an hour or so, and do it all over again. It wasn't quite magic, but it worked really well, and she was able to eat and drink on her own by the next day. Took a few days for her other end to start working as well--I was very afraid the insulation would just get caught somewhere else down the line, so to speak, but she's alive and well today! Best of luck to you, and I hope there's a happy ending to your story!
