Many people use the 57mg a pound dosage. An average hen weighs 4-5 pounds, and 250 mg is a good dosage. If she will take the capsule emptied into a treat, and take it all, that will work. Some use cream cheese or peanut butter on them to get them to scarf it down. But it is pretty easy to open...
Have you looked at her foot pads for any scabs or bumblefoot, and looked along the legs for any swelling, redness, or green bruising? A picture of both legs while standing might help. I would probably limit her movement during the days inside a dog crate near the other chickens for company, and...
If you get the acidified copper sulfate powder, you can give your flock a treatment of 1/4 tsp per gallon of water for 3 days a month as a preventative for canker. The treatment dosage is longer if you use it for that. Let us know how your chicken gets along, and she should be separated from the...
I am very sorry for your losses, but glad that you were able to get a diagnosis through a necropsy. Lymphoid Leukosis or big liver disease can be handled in a flock. @azygous, a long term member of BYC and an educator here also deals with leukosis in her flock. She may have some advice or some...
You are dealing with lice by the white lice eggs at the base of her feathers, and the elongated tan bugs. In Canada it can be hard to get permethrin dust or spray, or Elector PSP which are the 2 things I recommend for treatment. Your vet may be able to suggest a product. Your birds need to be...
I would agrre that she seems to have wry neck, a neurological symptom that can be caused by head injury, vitamin deficiency, is sometimes seen in certain viruses such as Mareks. Read my post in this thread for vitamins and where to find them for wry neck...
For wry neck I would use human super b complex 1/4 tablet daily crushed in food, along with vitamin E 400 IU given orally. A small amount of scrambled egg including yolk, would supply selenium to help the E. Neither Poultry Cell or NutriDrench has enough E to treat wry neck. Silkies are a little...
She may be experiencing a reproductive disorder because of the yellow material. Does she normally lay eggs? If possible, could you post pictures of a few more droppings? Do you wish to treat her for infection with an antibiotic in case she has a reproductive infection? Amoxicillin 250 mg twice a...
I would worm your chickens with Valbazen (albendazole) or SafeGuard. Ivermectin has been overused to treat mites and has lost some of it’s effectiveness for worms in recent years. Generic albendazole is easier to find than Valbazen online these days, and SafeGuard Liquid Goat Wormer is found in...
Did the cheese-like material have a bad odor? That sounds like canker (trichamonosiasis,) a protozoan infection. It can look like wet fowl pox, but it has a bad odor. The different treatments use for canker are metronidazole (flagyl,) ronidazole, acidified copper sulfate, and others. It is...
Since you have had Mareks I would keep a close eye on her. Bumblefoot is not that hard to treat, and there are many different ways of treating it. If you have any videos of her head shaking, and upload them to YouTube or a similar site, we may have a suggestion. Head shaking can be a way of...
Sometimes a full crop of liquid when a crop problem is happening, can cause rattly breathing especially if crop contents come back up into the throat if the crop is accidentally pushed or squeezed. Glad she seems back to normal, but keep an eye on her for any of the symptoms listed above in post 3.
SafeGuard and Valbazen are different wormers. Valbazen or albendazole dosage is 0.08 ml per pound of weight given orally once and then repeated in 10-14 days. That comes out to about 0.5 ml for a 4-6 pound chicken. SafeGuard Liquid Goat Wormer or the Equine paste are both 10% fenbendazole...
Can you telll us what symptoms you are seeing? Are there bubbles or foam in either eye, mucus from the beak or nostrils, swelling around the eye or face, sneeze or cough? Is there any bad odor? How does her crop feel? Have you added any new birds recently? Few antibiotics are approved for...
I would suspect an eye injury that has blinded her, and made her pupil that way. Usually with Mareks disease, the pupil may be small and irregular but the colored iris is dull or faded gray. Could you post a picture of her other eye? She may not be able to see well enough to eat. She may be low...
With all of the things you have answered, she may not be broody. Not laying, no missing feathers on her belly and chest, she doesn’t fit the symptoms. I would let her out of isolation and continue to observe her. Here is a list of broody behaviors...
That is a common place for injury from a rooster or pecking from hens, especially one that is new or bullied. Keep her separated, and you can get a small tube of generic triple antibiotic ointment at many Dollar Trees or dollar stores. Keep the wound clean and moist twice a day. Saline or a...
Oh I am sorry for your loss. I also recommend a necropsy by your state vet, to get a diagnosis. Have you seen any signs of mites or lice on her or other chickens? Her lower legs appeared very swollen, but with feather legged chickens, it can be hard to see the legs. Her urates looked a bit...
