Crops are normally full and firm at bedtime. But it should be mostly empty by morning. You can offer more coconut oil and let her drink water. Massage the firm material several times a day.
I would continue once a day to get it all out if possible. Do you have any Tylosin antibiotic? That can help if it was caused by a respiratory disease.
I would only give the antibiotic to a hen who has symptoms like hers. I would close your flock to new birds, or to any going out of the flock (don’t sell or give away birds.) She can survive, and would have a better chance if you can get the pus out of her eye.
If it is coryza, it is contagious, but the others by now are probably exposed. Have you added any new birds recently? You might try treating her with a sulfa antibiotic. Here is one that you can get...
I would try to remove the pus from the eye. It may not get better until you do so. You can you QTips and other tools. You may want to read this other thread where there are videos on removing pus...
Can you try opening the eye to see if there is pus or white material inside? Does she smell bad? Has she any nasal drainage, sneeze, cough, or noisy breathing? She may have a respiratory infection or disease, such as MG or coryza. Has she been picked on a lot in the past by the others? I would...
It does look neurological, or possibly from a seizure. That can happen with a head or neck injury, a vitamin E or thiamine (vitamin B 1) deficiency. Mareks disease occasionally may cause this, but silkies can frequently have wry neck. Treatment consists of giving human vitamin E 400 IU plus a...
No, I don’t think that is fowl pox. It looks more like small injuries. You could apply a tiny bit of iodine or leave them alone. The missing feather shaft could be from him pulling it out or scratching. I would look his skin over for any mites or lice moving around under his vent and belly...
Can you try putting the chicks with the broody, and see how they do? I would offer some electrolytes in the water. Some water added to a little dish of chicken crumbles and along with the usual dry crumbles would be good to get fluids into her.
The chronic eye foam is a sign of mycoplasma gallisepticum or MG, a chronic respiratory disease that also can cause infection in the reproductive tract. I have seen poops like that with hens who had salpingitis or reproductive infection. Does she still lay eggs? For her crop, I would check it...
Give her a human calcium tablet 300mg or a Tums broken in half orally. Then bring her in where it is warm, and soak her in pan of warm water, and see if she passes it. Try to loosen it from the skin, so she will pass it. Then I would repeat the calcium once a day for a total of 7 days. Most...
Is the scab on her breast bone (keel?) That is a common area for a breast blister which is usually from lying on damp ground or bedding or on a rough roost. It happens usually when a hen is not active, and spending more time on the ground or on the roost because they are sore. You can clean it...
I would start some Corid at a dosage of 2 tsp of the liquid per gallon of water for 5 days. You might want to bring them in for a few days for warmth in case they are sick. Symptoms of coccidiosis are hunching up, not eating, runny poop sometimes with blood, but not always, and weakness.
An abscess, such as from a dog or cat bite, sometimes may open on it’s own, but a feather cyst can continue to grow and get larger. I would probably lance it after disinfecting the skin, and then squeeze and explore it.
