My little phx hen who is about a year old went over her run a few days ago and back into the woods where I don't usually let them freerange. The next day she was hunched over and would not come out of the coop to eat. I felt her crop and it felt pretty full but not super hard. I couldn't find anything else wrong with her so I treated her with some olive oil and massaged her crop to see if I could get things moving being that is was that full early in the morning and she hadn't eaten yet. She was still acting the same for 2 days and not eating at all and the crop was still not emptying. When I was massaging her crop it felt like there were some little hard 'knots' of something in there. Yesterday she did not poop at all and this morning she had a few tiny off white thick liquid mucousy poops and that was all. I did get her to drink a little. Well tonight, I went to check on her and found this nasty thing in her cage. I had been keeping the cage spotless so I know she pooped it out. She also took a few bites of food tonight. I am wondering if this is what was blocking her up? AND what the heck is it??? It is tough and fiberous. It doesn't look like any of the pictures I searched for of poultry worms either. It isn't moving or anything. It is a little whiter in color than the photo shows. Any guesses to what this is?
