Worm them, and then make sure they're getting plenty of food and water. Might be influenza, might not. If it doesn't clear up after worming, or if sneezing and runny noses occur, then it most likely is influenza or a cold.

They can! When the crop of a chicken isn't working right, or when there's a lack of water, then this can occur. As to why your chicken died, is a mystery in itself though. Nothing I can think of that you're doing wrong either.

Yeah, it does sound like this little chick has a bug. You can get some soluble tetracycline, a broad spectrum antibiotic, from a feed store and add that to the water and see if that doesn't help. Since the chick is young, there isn't much you can do, and it is very difficult to pin exactly what...
I would be checking for signs of sour crop. Could be a bacterial infection of the crop, preventing good digestion. From experience, the crop can be empty, and still be harboring bacteria. Penicillin can be used, but it's usually pretty tough to get rid of, and can effect the health of the hen as...
If it's dark and snotty looking, then it's probably in early stages. If you wait around for the little parasites to eat the inner lining of the bowel, then you will see blood in the stool. Snot like substances are most likely from the body trying to fend of the parasite. There's a good chance of...
Sounds like influenza or worms. Most likely avian flu. Separate and quarantine as this illness is very contagious to other hens! Clean with bleach, and change all bedding. There is no cure for avian flu, and all you can do is make sure the hen is eating and drinking (fluids are important!), and...
Try a multi-vitamin supplement. Seems like something is missing in the feed, or maybe she's not digesting well. Pro-biotics can help with that as well.
What kind of feed are you giving to her? Is the crop watery-feeling, or bloated?

I've seen one-legged chickens do well as adults, so no worries there. I've seen this occur with chicks who are over-crowded, or do not have the strength to stand, and so trampling by other chicks occurs. Definitely separate the chick and do what you can. Some rehab, such as what you are doing...
Coccidiosis! Wash hands and make sure you separate this duck from any other animal! The stool from this duck is contagious!
Coccidiosis is a protozoa that attacks the intestines of an animal. It is carried from the feces and water sources where infected animals reside. Ducks are number 1...
Seems like something else is going on here besides wry neck. Wry neck is usually apparent much earlier in life, and at 16 weeks, feeding the grain you have been should have cleared that up. Although, you are feeding an organic blend, I would check the levels of vitamin E and selenium on the tag...
