Hi everyone,
i have a young hen (6-8)months old. Since yesterday morning all she does is sit on the floor not moving all day and stares up at the ceiling. She is so lethargic, she lets me pick her up, stroke her etc. even though she is one of the nervous/shy ones. Does anyone have any ideas what could be wrong. I´ll add a few pics shortly.
Thanks in advance
Mark
Hi, Mark ... most probably a thiamine (vitamin B1) deficiency, but there's also the possibility of toxins (botulism, algae, aflatoxins, etc.).
:: edit :: forgot to mention ... I'm differentiating from other deficiencies, and leaning toward thiamine over intoxification, based upon which muscles in her neck that appear to be paralyzed. Once you've treated her, and read up? You'll see why
:: /edit ::
As soon as you get this far? Go immediately 'n change out the water for an astringent solution of Apple Cider Vinegar at the rate of four teaspoons to the gallon (but not in galvanized metal containers). Don't even finish reading yet, unless you've gotta run to the store. In that case? Pick up some chicken-safe foods that are high in thiamine if she's still able to eat, or a thiamine supplement that you can dose her w/ as soon as you get back.

Now, back to the ACV ... most of the credit goes to the tannin it contains, as it serves to reduce the viscosity of mucus, and 'cuts through' the coatings in the mouth, throat and intestines. This is a treatment for toxic substances, but also an excellent way to improve the uptake of nutrients/vitamins, which helps correct this problem most quickly. For certain -- it won't harm a single feather, no matter what's goin' on w/ your bird, and it might save her.
As for the foods/diet? First off, you're gonna wanna consider all your birds as deficient at some level, and you need to stop the amprolium (medicated feed) if you've been usin' it. Most commercial feeds are somewhat deficient on the soluble vitamins, and thiamine is what amprolium blocks -- the coddicia are fifty times more sensitive than their host, but over time? It can sorta starve the chicken, too.
Ironically? Eggs are normally a great boost for chickens, but dairy products (esp. yogurt, or cheese) would be better. Crushing up sesame or sunflower seeds will help. But, way up at the top of every list: Yeast Extract Spread (Marmite) provide 0.5 mg of thiamine in each teaspoon full, and it's really high in riboflavin as well (which is most probably low as well). Initially, supplement throughout the day, since these are water soluble vitamins. Adding a supplement to the water as well is an excellent idea, under these circumstances.

> peck here << for Merck's general section on deficiencies, which is another good one to read, while you're watin' for your bird to improve. Riboflavin (vitamin B2) might be another concern, as diet are normally borderline deficient on it as well ... from this same link: Thiamine deficiency is most common when poorly processed fish meals are used, because they contain thiaminase enzyme. In such situations, adding extra thiamine may be ineffective. In regular diets, deficiency is prevented by supplements of thiamine at 4 mg/kg. <-- but this one needs considerably more.
