Hen with prolapsed vent laid an egg - Now what?

A couple of days ago, I [posted to backyardchickens](https://www.reddit.com/r/BackYardChickens/comments/1uakt5t/prolapsed\_vent\_needing\_some\_guidance/) about my girl Rita who is suffering from a prolapsed vent. The long short of it is that she was acting alright with the exception of not really wanting to eat or drink and the prolapse didn't want to stay in. It improved a bit since then and I only had to push the prolapse in twice yesterday. I'm treating it with honey, Preparation H, Vetericyn, and giving her Hydro Hen for probiotics.

​

She hadn't laid an egg in a couple of days when I posted, but she laid a soft shelled egg at some point late last night or early this morning and the prolapse slipped out of her again. Before this, it was staying inside for a good while; I only had to push it back in once during the day after she pooped. I had to push it in twice back to back this morning, but it stayed in after the second time, which was 3 or 4 hours ago. She ate a small amount of scrambled egg w/ calcium citrate but that's it. She seems more interested in eating the grit I put down for her than the actual food. She's still walking around and preening, and now she's drinking water.

​

My question is, what do I do now? Do I just treat it like you treat a prolapse normally? Aside from potential egg yolk peritonitis symptoms, should I be looking for anything else out of the ordinary?
