Sorry it has been so long since updating.  I moved her to our basement in a dog crate.  I changed her diet to wheat to prevent egg laying, gave her some probiotic and terramycin as per vet instruction.  I ended up putting her vent back in probably 3-4 times and then it stayed in.  I kept her in a few more days to keep her on a wheat diet and observation, then put her back in the flock.  Since then she looks 100%!  I'm kind of proud of myself lol!  Anyways, since then our egg production has become practically non-existent, so I'm not sure if she's started back to laying or not.  I'm trying to keep a good eye on them to see, but her vent is definitely staying in and looks great!
