HELP! Sick chicken!

[JLS42]

I have a hen that is about 2 years old. She is going bald on her head, random patches and completely red raw on her butt. She has scaly feet(parts are bloody), and I’m sure she is the culprit of the diarraha in the coop along with a egg without any shell. She is acting normal, very alert and running around like normal. I thought that she needed more Ca so I have been giving them their egg shells back but it doesn’t seem to be helping... Is this mites? She is the only one affected for about two weeks now. I can’t catch her for pictures at the moment hopefully I can get some pics up later.

Pictures would be very helpful.
If you suspect lice/mites this will help with identification, lots of pictures:

What breed is your hen? Hybrids start laying shell-less eggs after a couple of years.

She does have scaly leg mites. I use castor oil. Soak the feet and legs for 20 minutes in epsom salts, use a soft toothbrush to gently clean debris off the legs, try not to damage remaining scales. Dry them off and apply vegetable oil and then vaseline. I use castor oil and skip the vaseline, I just find it easier, less messy, and equally effective. I work the oil gently under the scales with the same soft toothbrush. I repeat the oil applicaton every other day for the first week, and then do 2 times a week after that until the legs look normal again. That can take weeks or months. The feather loss on the back of the head looks like rooster damage to me. If you don't have a rooster then a dominant hen may be doing it. The area on the back looks like there may be something around the base of those feathers, can't see it well enough, but I would suspect mites or lice. Use the link I gave you and compare what is there to the pictures. The link also gives treatment recommendations, usually people use a permethrin product, you will need to treat the birds, and the coop, and remove and replace all bedding. I also see at least one broken feather shaft, which could again be rooster damage or from a dominant hen, or feather picking, you will need to do some observing to see if those are issues also.

Thank you! Thank you! Thank you! I will get right on it!
