Backside, irritation

Can you wash the bird's backside to get a better idea of what that is? It might be a small prolapse but it's hard to tell with all the other in the way.

I'm going to holler @dawg53 for his opinion too.

Tough to tell. Any picking going on from other birds? Small prolapse is a possibility.

It can just be diarrhea from giving her yoghurt. Best to clean the area to see what's going on.

I cleaned it. Applied antibiotic cream and pushed it back in. I was told it may be open vent? Anyways , the next day it came back out again. I repeated by steps and it came out again the next day. Not sure what to do now. It looks bad!

Use preparation H. It will help reduce the swollen tissues.

Is she laying? If that is a prolapse and she's continuing to lay it will keep happening. The only way to stop her laying is to shorten her days by reducing the light she's getting.

Thank you.

She is laying eggs. I suppose I have to find a box to put her in and close it to reduce the sunlight. I will also try the preparation h.
is this the most effective method to fix this issue ?

Pretty much. Honey is also used.

If you can put her in the garage with no light on. Her coop with the door shut. Just shorten the hours of daylight she gets to slow her egg production. She doesn't have to be up all day. I'd have to look but the hours need to be something like 8 hours of light to cut production.
