Hopefully she will be able to pass the necklace. You have some good suggestions on your thread, they can be found here:My chicken
, we took my chicken to the vet and turns out they did X-rays on her and she has a necklace in her intestine. Will she eventually be able to digest it or pass it? Maybe throw it up or poop it out? What could I do?

I would not rely on ACV to break down metal in the digestive system. It *might* cause metal to rust, but it surely will not dissolve it.
Chickens ingest metals which can cause an assortment of health problems in time. There's even a name for it, it's called "Hardware Toxicity".
Give her apple cider vinegar in water and chopped up tomatoes. The acidity will help break down the metal and hopefully your chicken will survive.
It could help break it down so it doesn’t cause physical damage or obstruction to her digestive tract leading to death, which is the primary concern right now. I’m not sure about metal poisoning if she does survive. I don’t think she’ll get parasites from it though. How is she doing?

she’s more active again and happy. She eats some of her chicken feeding again, we give her yogurt and house food. As well as bread and other snacks and treats she loves like greens, veggies, and fruits! She doesn’t eat AS much as before but her eating is picking up again. I honestly thank all the prayers I’ve been doing they have been working! She’s been pooping much more, not as much as before but much much more
