Chick not wanting to stand

[BirdLeaf]

(Forgive the mess, it’s food grade DE)
I have a month old chick who keeps falling over or laying down. Poop is normal, appetite and water consumption is normal (if I pick her up and put her by the water or food), but she can’t even sit upright.

Earlier she appeared to be shivering but has since stopped. No signs of illness or lice/mites/fleas and the rest of the flock is normal.

She’s hanging out with an injured chick currently since she was being trampled, none of the rest of the chick flock is showing any signs of illness at all.

Any clues as to what this could be? Thanks!

I'm sorry to say this but from the chick's position it looks like Marek's to me.

Ahhh I hope not. I hatched her from my own stock. No other birds are sick. Her only symptom seems to be she forgot how to use her legs. Seems like she’s flexing them straight out at times.

I hope not too!

It looks like you're free feeding chick crumble, correct? So it probably isn't a vitamin deficiency unless you happened to get a really old or bad bag, can you check the date on it to make sure? BTW, I don't have experience with this, just trying to help figure it out with you as best I can.

It says it was made on 9/27/2017, best by 6/27/18. She’s eating plenty, and drinking lots too. It’s just so weird to me, seems like she’s totally normal other than her legs. When she tries to move she looks like a fish out of water. She’s really liking this extra soupy mash though

Looks like Mareks to me too. Doesn't matter that you hatched it yourself. Mareks can blow in on the wind or be brought in on wild birds.

Feed made 9/27 is too old, IMO. Can you go get a bag of fresh feed? It does look like Marek's, but seems a little young for. If it were my bird I would weigh it daily and watch for weight loss, or not enough weight gain, and I would start giving it some Rooster Booster Poultry Cell orally.

It does looks a lot like Marek's, but I have never seen a 4 week old with it. .
