It would be best to see an actual picture of your chicken. Terramycin has become hard to get without a prescription or vet. I have used plain Neosporin/triple antibiotic in my chicken’s eye. Some people who have cataract surgery may have some leftover antibiotic ointment.
It looks like feather picking. Others may do this to her while they are hanging out or on the roost, or she might be doing some herself. Overcrowding, bullies, boredom from not getting out to roam, or too little protein in the diet can be causes. What are you feeding? Look over her skin under...
Arteries would be deep. This should be able to be lanced on the surface, and using fingers to squeeze or manipulate out the material. I think that you will do fine. Pressure for several minutes will usually help the blood to clot. Most feed stores have disposable scalpel sets if you ask for them.
Be careful visiting a friend’s farm who has had Mareks. It is spread in feather dander and dust, and may last in the area for years. The best way to get testing is a necropsy on a chicken by your state vet lab where they look for tumors, and do feather shaft testing. Other testing can be done by...
I have only seen feather cysts online, but that is probably what it is. It may contain a mixture of sebum (oil,) skin, and feather material inside if you remove it. Here is a video of a vet removing 2 of them:
You know that is an injectable cattle antibiotic that is given once into the back of the neck or into the breast muscle, and if needed, repeated in 3 days? Some do try and use that orally, and that is a pretty small amount to give orally. I would hold her in my arms, pry the beak open and...
If you have birds at your new place who who were exposed to Mareks, they are carriers. It would be difficult to completely sanitize your area. It can remain in the environment for years in the dust and dander which spreads everywhere. Did you have the Mareks confirmed with a necropsy and testing?
He may have a injury with some nerve involvement, a vitamin B2 (riboflavin) deficiency, and more rarely Mareks disease can cause this nerve problem which can be curled toe paralysis. Hopefully, it isn’t that. I would crush 1/2 tablet of human vitamin B complex in his food daily. Here is one that...
I would treat her for mycoplasma (MG,) which can cause swelling and a foamy eye. First, rinse the eye with saline or eye wash, and apply a small dab of either Terramycin or plain Neosporin ointment twice a day into the eye. Tylosin powder can be added to her water 1 tsp per gallon of water for 5...
A dirty vent doesn’t mean she has worms. She may have had some runny poops, and you can clean her off with soap and water. If she gets messy often, you can slightly trim any extra fluff.
Calcium citrate with vitamin D 300 mg is available at Walmart (and most stores) in the vitamin aisle in the pharmacy area. Tums can work, but has no vitamin D. You can worm her when her prolapse is better. Keep her clean and keep the prolapse tissue from drying out with ointment.
Fowl pox usually lasts about 3 weeks. Hopefully she can see well enough to get food and water. I might let her have some visits with her flock so that she doesn’t have to be reintegrated later.
