hen of 6 months sick help

[grandmas Nest]

I lost one hen about 3 weeks ago, now today I have another one sick. Yellow runny poo, she is laying on the coop floor and when I try to make her stand up she is unbalanced. I got the shot for Markes when I bought them as babies in March. All seemed fine yesterday. They are not free ranging. They have sand in there run. There is no blood in poo. I can't find anything that they could have got into and I can't find any sign of worms in poo. Also I put DE all around in coop so it shouldn't be mites. What else can it be?

What are they eating? Could they have gotten into moldy Food? Worms, maybe? Vitamin Deficiency? - Worms may not show up in their poo.

The one that is sick I seprated and put mothers vinigar in her water which I got her to drink a little but she hasn't moved at all. What do I use to deworm them and do I have to throw the eggs out? They are on a commercial layer pellet food. Then I give them cabbage, and stuff like that out of the garden.
