Repecka has Diahrea

I know I've misspelled it, but she does have a good dose of it.  We've isolated her, given her fresh water, chicken mash made soupy with water, and some meal worms to perk her attention up.  She's lissless.  We've put a few drops of Life-Guard in her water and Limestone flour in her mash.  I don't know what else to do for her.  Any help would be appreciated. 

Hi!  My hen is two years old.  The D is clear with some white in it.  She's had a more solid squirt since the post and hasn't pooed in about three/ four hours now.  She also had a massive drink of water since then.  She's still very dopey though.  I wonder if it is the heat? 

Thank you!  She has perked up this morning.  But she tried to pass something about an inch long and it receded back into her vent.  She was really straining to pass it.  She passed a soft shelled egg three days ago.  I am thinking it might be the remains of that.  She's back with the rest of her flock and is taking interest in her surroundings, drinking water and eating.  Fingers crossed she passes whatever it is, unless its a prolapse.  I pray it isn't that!

Thanks Joyful!  She's just about normal today.  After losing Molly just two weeks ago, we are a bit paranoid now.
