Dosage of many meds can be higher per pound in chickens, especially some of the antibiotics. Casportpony’s info came from Plumbs Veterinary Manual which is pretty good.
Nystatin dosage is 200,000 to 300,000 units per kilogram (every 2.2 pounds of weight) 2 to 3 times per day. I would probably start with 4.5 to 5 ml twice a day. Here is a thread from casportpony about dosage...
I would not cut into the chicken. How old is she and does she normally lay eggs? More than likely, she has salpingitis where she has lash egg material inside her. Have you tried ro give her a human calcium tablet or Tums to help her pass an egg or lash egg? Is she eating and drinking fluids? Is...
Is she pooping? Have you tried to hold a small cup or tin up to her beak every 2 hours to drink some sugar water or fluids? Dipping her beak may get her started. Very watery chicken feed with a little scrambled egg might tempt her as well. How does how crop feel? Is it emptying overnight? Is she...
Is she drinking and eating some today? I would offer fluids and some moistened chicken feed up to her beak often. I even put water on softened scrambled eggs to get more fluids into them.
Glad to near that she has returned to normal. I had a hen who would get stridor sometimes by inhaling her chicken feed and eating too fast. Then she would be fine in a few hours. Make sure the feed is not too powdery.
Welcome to BYC. Is the hen new or picked on? Was she pecked or injured by flock members or was she out where she was attacked by a predator? Is she in shock? Keep her separated and away from flies. Keep the wound from drying out with the antibiotic ointment twice a day after spraying with saline...
Sorry about your very sick hen. Do you plan on getting a necropsy on her through your state vet? That would probably give you a diagnosis eventually. What state are you in?
Good advice from coach723. Has she eaten anything lately? Besides the fluids which are most important, you could offer some watery chicken feed with a little egg. The tiny poops are concerning. I would not soak her anymore, but hopefully the calcium/Tums will stimulate her to pass an egg or lash...
I am not a vet. It looks like some additional testing is pending. The secondary diagnosis was necrotic enteritis, which can be common in coccidiosis. Enteritis comes from an organism in the soil and the gut, usually clostridium. It responds to certain antibiotics such as amoxicillin, tylosin and...
That is a new one for me. There are a lot of abnormal eggs seen, but that one is unusual. Have you heard any frequent sneezing or had any stress in the flock?
It might be a collapsed egg membrane. Do you see any cheesy material inside if you cut it open? You could give her a human calcium tablet with vitamin d or a Tums orally daily for a few days to see if it helps. Is she starting to molt, or have feather damage from a rooster? Here is a good buy...
She sounds like she has stridor, a sound when a small piece of feed or mucus gets stuck in the airway. Usually this clears up in a few hours, but if it persists, look for watery/foamy eyes, head shaking, nasal drainage or mucus from the beak. Those are signs of a respiratory infection or disease.
The most common wormer SafeGuard or fenbendazole liquid goat wormed can cause feather problems if given during a molt. Albendazole or Valbazen which is harder to find, but available online may be used. Dosage is 1/2 ml for most 4-6 pound chickens given once orally, and repeated in 10-14 days. It...
It is always good to start a new thread of your own, so that more people respond, and info does not get repeated. The dosage for enrofloxacin (which is banned by the FDA for chickens because of emerging antibiotic resistance) is 10 mg per every 2.2 pounds of weight given twice a day for 5 days...
It could be her sister on the perch picking at her feathers. Many times the picker will have perfect feathers. Spend some time during the day and in the evening with her and watch. I have seen a few of mine doing this on the roost in the evenings. Look her over for any lice or mites if you...
How old? Is she molting? It may be feather picking which can lead to cannibalism. It can be caused by over crowding and boredom, not getting out to free range. Feeding a 16 or 20% protein balanced chicken feed is a must, and limit any scraps or extras. Scrambled egg bits, tuna, or increasing...
I would get some Betadine or Hibiclens chlorhexidene at Walmart and clean her wounds twice a day with half strength. Then apply plain Neosporin triple antibiotic ointment twice a day. Is she drinking fluids and eating? Can she stand and walk? Is she still in shock?
It can be difficult to get antibiotics without a prescription. You can try here for amoxicillin:

How old is she? Is her tail position down? Is there any swelling or fullness around her vent? Is she walking with a wide gait? You can try to offer her a human calcium citrate tablet with vitamin d or a Tums orally. Pop the tablet into her beak, or break the Tums in two and give her that. Offer...
