pullet not thriving, malabsorption?

[henhubble]

Hi, I have been given a couple pullets with problems. The lady made her own feed mix, Austrian peas and barley, and I don't know what else. Would this be sufficient? One has wry neck and the other can't walk and is still fairly emaciated after two weeks. She eats well enough, we have commercial feed and also meal worms and egg yolk, but yet her crop never seems to fill. She sits and sometimes squirms, but is unable to stand although her neck and wings and tail all can move. I have seen her legs move, but seldom. Her poop at first was diarrhea but then became kind of dry and puffy, then normal. Now it is sometimes runny with yellow in it but I think that is the egg yolk. I thought it was something to do with her hocks which were swollen, but I don't know what it is.
Is it malabsorption? The lady got too many chicks and I think they were overcrowded and then put out in a small shed and the weather was cold for February here and all they had out there were 100 watt bulbs (hope they were 100 watts) and the chicks were about 5 weeks old. so I think stress due to overcrowding and chilling? Or improper diet?
Pullet with wry neck slowly improves, but she still has balance issues and seems to have a slightly bent body and neck alignment. Otherwise she is lively and getting bigger. The abovementioned hen concerns me most, she is alert but not active. We give her baby aspirin, a fourth a tablet as she is so small. We got her some gel vit E 200 IU (no 300 IU tablets at store) and we also have been putting chicken vitamins in the food. I think she was on the brink of dying when we got her and she has improved in appetite, but I was hoping for a faster recovery. Chicks were not vaccinated against Mareks but I think they would have died by now if it was Mareks. The rest of the 60 plus chicks are well enough, although I don't know if they are growing as fast as they should.
any thoughts?
Please help, this little black australorp pullet needs help

So are they around 2-3 months old now? Do your vitamins have riboflavin (B2) in them? Swelling in the hocks could be from slipped tendon or leg bone deformity, but also can be a sign of an infection, such as mycoplasma synovitis or viral tenosynovitis. Wry neck can be due to either thiamine (B1) or E deficiency, but also can be hereditary or due to a head injury. It can be a symptom of Mareks disease in chickens old enough to become symptomatic.

You might try a chick chair or sling for the one who cannot walk. It would be good to see what the legs look like in their normal position. Here is a good link for ideas of homemade chicken slings, and the basic design is below:

Thanks, yes, the entire B complex. I will look up the two synovitus diseases.

She gave us a cockerel a month ago because he had broken his leg, or sprained it, and although he Had recovered, the others shunned him. Now my son brought another RIR like that one which has a broken foot and the difference in their sizes is considerable. My son said all the ones she has are smaller than the RIR cockerel she gave us a month ago. I think it is all stress due to overcrowding and not enough water or feeder space. I added the gel Vit E and I really hope that makes the two better and I will try to get my daughter to take pictures with her I phone. The little black one's poops are rather soft with yellow in them. I think that is the egg yolk. It seems like there is some clear liquid as well sometimes. Thanks for all the help. Now to splint a foot and possibly the leg as it bends inward a little as well and keep it up off that foot

I am slightly encouraged as the little black pullet seems to be trying to stand up. She seemed like she just let her legs hang for a while, but now she moves them more, but usually ends up just sitting on her hocks. Still this is an improvement! Her one hock joint is still a bit swollen, but she has a good appetite and seems increasingly mobile. I shall hope as she is such a sweet little girl
