Silkie with mites! Acting sick....possiby anemic.

I was given two silkie hens that were almost a year old about a month ago. The previous owner said they had mites and had been treating them for them so I continued to treat them after that and then one started acting a little weird one day not coming out of the coop and kind of sitting in a nesting box/corner. If I would put it in the yard it would peck around and eat a drink normally so I thought maybe she was broody. She did that for 2 days and then I was looking at her to find she was still covered in mites and she didn't make it through the day. So my guess is she became anemic from the mites. Anyways, I have thoroughly treated the other, bathed it, cleaned out the coop extensively and have been checking the one that lived for mites regularly. She has been acting normal and I haven't seen any mites on her but today she seemed like she was starting to act a little like the other one had so I checked her and found just a few mites on her so I bathed her again but I'm wondering if this is the same thing going on with this one if there is anything I can do to save her if she is anemic. I made her some eggs that she ate and I gave her some spinach and she's been drinking at eating her other food normally today and pecking around. I can just tell something is off with her and want to try everything I can to make sure she'll be okay.

Anyone have any advice or ideas for me?

I have used Adams Flea and Tick shampoo on mite/lice infected birds. You have to do it once a week for three weeks to get everything that could hatch out. My birds love a bath.

I have had good luck using ivomec injectable externally, too. Use eye dropper to put couple drops on top of head, under each wing and at tail vent. This does not deworm chicken, but does get external mites/lice.

I use Quest Plus to deworm by mouth at about one tenth of a CC per bird. Have used more without any problems.

Permectin is a pyrethrin concentrate you can dilute and spray coop. Read label as this is handy, useful, and fairly safe insecticide.

Find vitamin drops labeled for birds. You want B vitamins and iron as this kick starts red blood cell production. Red Cell might be labeled for birds.

Does your bird have any company? They can decline if lonesome due to stress. A bird feels safe in a flock.

oops, forgot to add on feather footed birds you need to put drops of ivomec on each foot, too.

Those feathered feet can hide lice/mites so really pay attention as you treat.

Thank you!
We have a lot of chickens but they are still young. She was very attached to the other silkie that we lost early. They had been together since being hatched and she has seemed lonely to me at times without her...
I hope she pulls through, she is such a sweet chicken and we love having her in our flock. Hopefully I can find somewhere to get those things tomorrow!

Feeding her a bit higher protein can help, too. They need that for making RBC to overcome anemia. Something like the 'showbird' feed that i think it is Manna Pro, sells in five pound bag. Treats of boiled or scrambled eggs, cooked meat help,too. Is she still laying and has she molted? Both are extra stresses on her. I know what you mean about what sweeties silkies are, like tribbles with legs.

Have lice/mites spread to your other birds?
The Quest plus is horse dewormer and $13 a tube. Ask around your friends and neighbors that raise cows,goats, sheep and see if they have the plain injectable ivomec as a bottle of it is about $40 and would last you forever. The Quest plus might work externally same as liquid ivomec as both are same family of dewormer.
Research life cycle and treat to interrupt, usually that's 7 to 10 days.

So far not had any major issues of lice/mites in birds. But, have been through gosh awful outbreaks of ringworm years ago that affected my horses, cats, dogs, goats, us too. Only thing not affected were cattle and fowl. You ever tried to dip a cat? Take a tall lidded trash can, fill 1/3 with dip solution, catch cat and with lid at the ready, drop cat into trash can, be very quick to put on lid, shake a bit, remove lid and slightly tip can to allow rapid exit of cat. Repeat weekly for at least a month. With something like this you have to treat all affected species, even if not showing symptoms or they just spread it back and forth. A feral cat was first case in neighborhood and it spread from there. Makes me itch just remembering.

I've been giving her scrambled eggs and meat ground up in my food processor with broth mixed in. She seems to eat a good amount when I give that to her. I also made her some sugar water that she has been drinking. After eating some meat this morning she came out of the coop into the yard and pecked around a bit and then just went and stood in a corner which is what she was doing yesterday that started concerning me. The lady I got her from said she is about a year old and hasn't started laying eggs yet. I don't think they were taken care of well when I got them. They were dehydrated, had poopy bottoms, and were totally covered in mites. It's so hard to tell what is going on with her, sometimes she is acting normal and sometimes not. I'm not sure where to start!

And none of the other chickens have mites and I havent seen any in the coop. The rest are all acting normal.

Keep an eye on others birds as mites/lice do spread. Years ago I bought a small flock of mixed breeds and they had various parasite problems due to naive owner. Basically I dewormed with quest plus once a week for three weeks and used permectrin mix to spray coop and roosts. At the time they were only birds I had here at the house. Wild birds have lice/mites and it is impossible to prevent contact if your bird free range. I try to look at my birds real close every week to make sure they have not picked up any hitchhikers.

Make sure she has some plain water to drink, too, along with sugar water. Can you get her to pick grass or anything else that is green? Sprouting grains/seeds take a few days to grow out and are great for birds. It is hard to say what is going on given her history. She should have started laying at about 5 months of age. She may have had a hard start, but you sound like you have done right by her and her sister. I hope she makes a recovery.
