Actually I feed them scratch and peck feed. Organic non gmo I do not want to switch to nutrena I will look for a different organic or non gmo feed. But I noticed when I get the powdered stuff that's left and mix with water and gets mushy she eats that fine.
Well, @Mike10 , you can take the stuff you like and put it through the blender or food processor, perhaps.
It's hard to guess what's wrong with your chicken long distance, and I'm certainly not a vet, nor even anything approaching an expert. Other folks on here have far more expertise than I do. But here's what I understand (and maybe I'm wrong):
Your hen looks and apparently feels unwell.
Your hen has watery, green and white poo that has had at least some blood in it, as well as undigested whole grains.
Your hen's crop is hard, and possibly somewhat swollen.
You have just administered Safeguard (fenbendazole) for worms, and are treating for coccidia.
You are feeding a "scratch and peck" feed which I suspect has a lot of whole grains in it, and which is probably difficult to digest.
So maybe someone more expert than I am will chime in here, but my very amateur guessing is that your hen may be having trouble digesting the scratch and peck feed. The difficulty in digestion could be related to crop problems (see posts 164, 165 & 166 from @casportpony ), which may also be related to worms, or coccidia, or both. The worms and coccidia can damage various parts of the digestive tract, and can also impede digestion. Or if the crop is impacted from undigested grains, or has soured, that can be an additional or a separate reason the hen may not be feeling well. Excess/impacted food may need to be removed or flushed through her, or she may need antibiotics or some other treatment.
It seems like in addition to the very good start you've made with worming and treating for coccidia, that it would be worth checking out what is going on with her crop, if anything, and trying to figure out if she would benefit from some treatment for her crop. If it progresses, she can end up with permanent damage as explained in post #166, above. With her intestinal tract not in good shape, and her crop getting hard and swollen, she probably really needs soft, easily digestible food while she gets back on the path to wellness. So if you can help your pal out by grinding up her grain for a bit, you might save her life while you search for the source of her troubles.
My first, last, and best advice at this point is that you take your feathered friend to an actual vet who treats chickens. Again, if she were a pea, looking as bad as she looked in the photos, I'm afraid she would already have died. I dunno about chickens, she seems to be hanging in, fortunately. Good luck with her
