If she can't see she's probably not able to find her way in. That is why I keep mine inside the run in a separate area. She doesn't have to find her way in and is secure. It very much depends on your particular set up, space you have, etc. But if a bird is blind, allowances and...
The fastest and most humane method is cervical dislocation. Other ways may be "better" for the human, but not for the bird. It needs to be as instant and painless and panic-less as possible. How I do it is outlined here...
Vaccinated chicks should not be given the medication unless they have symptoms that require treatment. Treating unnecessarily can negate the effectiveness of the vaccine. The vaccine is usually a spray on that they ingest, and then when exposed to the coccidia they develop resistance without...
Feathers take a lot of protein to make, so a higher protein feed can help. They make a feather fixer feed, or if you are feeding layer feed, which is usually 16% protein, you can switch to an all flock or grower feed in the 18-20 % protein range. High protein treats, like scrambled eggs...
Sometimes it's a solid kernal, sometimes it's more stringy and it tunnels through the foot. For those, I've found the sugardine to work the best. The pus is often is adhered to the healthy tissue and can take some manipulation to get it unstuck. My advice is to take your time, work slowly and...
It's very hard to say without knowing what it was. It could have been something that won't affect the others at all, or it could have been viral and might. It's a very good idea when you lose a bird to something unknown, which might affect the flock, if possible, have them necropsied with lab...
I have a rooster that lost part of a toe, looked similar to yours. That was a couple of years ago and he does just fine now. I basically did as @Eggcessive described above. He now has a stump with no nail, and it hasn't affected him at all. As long as there is not infection, he should be ok.
What to use depends very much on what particular pathogen you are dealing with. Some recommend a bleach solution, Virkon S is a strong disinfectant that works on many virus's. Many of the respiratory illnesses are very contagious, so depending on what you were dealing with, the others may...
That is either bumblefoot or it's dirt and droppings that has imbedded in the foot (commonly called mud balls). The bottom foot may be mud balls, the top one I suspect is bumblefoot. I would soak the feet to soften it up, and clean them off well, a soft toothbrush works, and get a better look...
Lots of info and images here on identifying lice and mites:

Skin that is exposed to light will often be red, doesn't mean there is a rash. If it's on her underside it could be feather picking by others, rubbing on a roost...
If it's a pill or capsule, then you can just put it in her beak and push it back, she will swallow it. Size is not an issue, they can swallow a frog. If you have a powder then you could mix it in a bit of moistened feed so it sticks, but you'll have to make sure she eats it all and gets the...
I would get her on a calcium supplement ASAP. Citracal +D or generic equivalent, 600-800 mg a day, once a day. That form is better absorbed. That will help get calcium levels up for shell quality, and help with contractions to help her pass anything else in the pipe. Soft shelled or shell...
If she's 1 1/2 she may not have done a full adult molt yet. Likely that will happen sometime this year, usually late summer or fall, but sometimes dead of winter. I would wait for that, and see how she looks after. Feathers can get very worn and ragged and faded before they molt and get new...
If it happened during the day, then a hawk could be the culprit. Maybe a young one that is still learning to hunt and not very good yet. Lucky bird. If you have a game camera, I would see if you can catch pictures of anything that comes back.
If it was a hawk, it will probably be back.
I...
It may be splay leg, but I can't tell from a still picture. It needs to be hobbled to hold the legs in a normal position, and periods in a chick chair might help as well.
Examples of chick chairs here:

It may be pox, I can't zoom in to see closely. If it's pox, they will slowly darken and dry up to scabs and eventually fall off. Most birds do fine with no real issues with the dry form (which this appears to be). For birds that get the less common wet form, it has lesions in the mouth and...
If you are interested, there is a very good video on coccidiosis here, just under 13 minutes long, explains the disease, how it affects the birds gut, etc., very informative :
