Giving calcium has not helped her problem, so it may not be good to keep giving it. Usually a week or two of calcium is done, but giving it long term it can affect the kidneys. Her shell gland in the oviduct may not be working due to inflammation (salpingitis.) You may want to ask a local vet to...
Could you include some pictures? Do you see any maggots on the wound. Many times in hot weather flies will lay eggs on messy vents or in wounds, causing flystrike, which can be deadly. Let us know what you find. Most wounds (without flystrike) should be cleaned with a disinfectant such as...
I agree with Wyorp Rock in treating your chicken. There is no reason to put a chicken down who just has the dry form of fowl pox. Use ointment inside her eye, and carefully apply Betadine 10% to the scabs with a Qtip. Wet pox can cause yellow lesions and gunk inside the beak. If she does not...
Sorry that you lost her. I would disinfect all equipment and the area she was in. Coryza incubation time can be as little as 2-3 days, so watch your other chickens for symptoms. I would separate any with symptoms, and treat with sulfa antibiotics. If you lose another and get a necropsy by your...
The avian vitamins may have caused the green bile and yellow in the poo. It sounds like she is doing better today. Let us know how the droppings look once the avian vitamins are out of her system.
Yes, it looks like some lash material, which is from salpingitis (inflammation of the oviduct.) Can you cut it open and get another picture of the insides? Do any of the hens seems more sleepy, separating themselves, weak, or holding their tail down? If you can identify the hen, a human calcium...
I would give the calcium or half of one. 300 mg is good. The yogurt also has d 3 too which helps the calcium. It would be good to see some normal material in the dropping. It looks mostly like urates and mucus.
The6 can sometimes have another egg coming right along behind one that might have been slowed down because of shell problems. Hopefully, she is okay and it is just something temporary. Tums or a tablet can be broken in half, and just dropped into the beak to swallow. Here is one of many videos...
Sorry for your loss. Have you added any new birds in the last couple of months? Could she be starting to molt? I would offer some scrambled egg and wet mushy chicken feed, and try tuna or canned cat food to tempt eating. Offer some water with electrolytes a tsp of sugar to give her a boost. Is...
Do you have any Poultry NutriDrench or some electrolytes with vitamins to offer her? A human calcium tablet or Tums may be given to give her a little boost of calcium in case she is trying to lay. Have you seen any soft or thin shall eggs? I would keep an eye on her and her droppings. A bit of...
Do you think that you got close enough to the pus? I would recommend using Terramycin eye ointment or plain Neosporin triple antibiotic ointment twice a day. Hopefully, @casportpony can advise on the wound.
