Couldn’t walk last night, can’t stand this morning

I

Not pooping at all?
I would work on hydration first before he eats a lot. If you have electrolytes I would offer those.

I’ve put electrolytes and vitamins in his water. I’ll try dropping some in with a syringe

It is important to get them drinking and hydrated before eating. Once he is drinking, then offer watery feed. I would have to agree that Mareks disease could be on a list of possible problems, but dehydration, coccidiosis, and other things could be possible. The way the left leg goes out looks suspicious for Mareks. But leg bone deformities or injury might be possible. Make sure that your vitamins contain riboflavin (B2.) You might be interested in making a chicken sling to get him up and in front of food and water. Here is a good link about slings:

Okay I have syringed 5mls in to his mouth, I’ll take his food away. I have some watermelon, could I offer that?

I have that cat carry box! I could make that one- need to get a little water pot to hang within reach though. I can do that later today, thanks.

Yes, you can give him a little watermelon.
Either one of those products would be fine to give him. If giving the watermelon and he takes it, I would give the vitamins.

His left leg is the worst, it hangs down when you pick him up, the right is tucked up and moving more normally.

Does he seem to indicate discomfort or pain if you gently manipulate the leg that hangs?

 

[Bluebellhoney]

The 5mls I syringed in to his mouth had vitamins and electrolytes in. He resisted most times but also just sat with his eyes closed and didn’t react at all at times. He isn’t usually very tame so this is odd behaviour

I tested this this morning, he did jerk awake at one point around his “ankle” but I couldn’t replicate it. He seemed to rather enjoy the massage the rest of the time.

Oh good. I would work on hydration. Offer him some plain water too, some birds don't like vitamins and just won't drink them. Watermelon is good so if he will eat a bit of that it will be fine.

I wonder if it's injury, but you should get a reaction every time you move the leg. Marek's would be a possibility.
See how he does. Hopefully he will be more comfortable in a sling. I would move him in/out of it so he can change positions a few times a day.

Poor little guy
