Should you try to make a chicken with a sour crop vomit?

[Novice Chicken Mum]

One of our hens had a impacted crop that turned sour, so it feels very squishy. The crop has has been draining liquid, we know this because she is pooping out water and the oil we are giving her to treat the impacted crop. This hen is about 4 years old. Since her crop is so full of liquid, I was wondering if we should attempt to drain her crop, because I know some people who say to do it, and others who say not to. We also started her on miconazole. Thanks for any info!

This thread is a bit old, but my 2 year old silkie had a huge crop and we saved her! Its day 3 now, but i basically gave her a warm bath and massaged her huge crop, then once blown dried we gave her a dose of oil and kept her in a crate with liner and straw and a small bit of water. followed same next day with some yogurt and today little bits of bread soaked in olive oil. what a difference and she has been pooping and weeing normally. I am actually surprised. I also dabbed some clotrimazole (just household thrush cream) on her vent after the bath, because she definitely had thrush before this happened with the crop. (I think it was the bath and massaging, plus dosing with olive oil that really made the difference) but she wasn't very very sick just subdued.
