It was a thick cord out of my curtains. Not just a string. The size of a drawstring for pants or a winter coat and quite a bit of it. I was fortunate that it was not metal. It took the full 48 hours of every two hours administering it for it to finally pass. Good Luck with your Chicken. I do know how you feel as my Ducks are like family to me also.They offered surgery for us but it’s 100% risky and she wouldn’t make it. For us it was $600 with the X-ray and medicine and draining. My mom got a laxative for the chicken I’ll see it it works but she ate a necklace that’s the thing. What did your cat eat again?
