Sorry you are having this problem. I'm glad you sent a hen off to a lab. It's better than all the guessing.
At the bottom of my posts, please read "The big Marek's FAQ". That's got tons of information in it, and was written by Nambroth.
I think the mash and yogurt were fine.
Wasting, unfortunately is a symptom of many illnesses. And lameness/paralysis can be a symptom of other illnesses too. I think the first thing to do is see about your flock history. Like who got added a month or two before you had a sick chicken?
How many chickens, how old, have they been wormed regularly and dusted for bugs?
Are they on medicated feed?
If you hatch your own eggs, hatch in a room that has been seldom used. You would need to buy the vaccine, and give each chick an injection of vaccine. Then quarantine them for at least 3 weeks and the longer the better. I spent 3 weeks gowning and gloving to take care of the chicks because my flock has Marek's and it's probably all over my house as well.
You can try a multi vitamin for now. Like multi B vitamins.
I have 21 chickens. I have 4 D'uccles, the roo is a D'uccle that has the leg issue. They live with 2 silkies and the one deceased frizzle, all in one coop. All of these are from this year's chicks. The frizzle and 2 of the D'uccles were bought back in June.They were around 8 weeks old then. The silkies , I hatched (along with a few of the laying hens). I bought the oldest D'uccle at TSC as a day old chick. The D'uccle roo was bought about 2 months ago, I isolated him for a few weeks and then put him in the bantam flock.
I have 13 egg layers and 1 roo that free range all day and go in another coop at night. One of these was the "wasting away BA." 6 of the laying hens are from this years chicks. One, the BA, died. One went through a week or so of not eating, but recovered. The other 4 are fine. I have 7 older hens and the roo, also from this year's chicks. All are fine. I also have 1 cockerel in a bachelor pad (last one from the year's hatching), he's also fine.
I have not wormed them since last fall. I have the supplies to do so now. I intend to worm every fall. I do not like doing it because I have to buy eggs for an entire month!! So I have put it off... I use DE in and around the coops. I dust as needed but as little as possible. I have had lice on them from time to time. It's been the biggest issue I've had, one much easier to deal with than whatever this is!
The egg layers free range over several acres around my house and in the woods/pasture. We have 9 acres here. They eat countryside organic layer. The bantams eat a mix of the organic layer and southern states game bird feed, the higher protein one.... The feeds are non medicated
