3 Yr Old Hen Walking on Hocks, Thin

[Stephine]

Argh. Came to the chickens this morning to find that my three year old Brahma hen Penny is wobbly walking on her hocks. What on earth? Picked her up and found she is thin, too, well hidden under her fluff I have to say. Comb and wattles look nice and red, some poop stuck to feathers in her tush - but all my Brahmas have that - they have a lot of fluff there... She is vaccinated for Mareks - what could it be? She had trouble with b vitamin deficiency as a chick (tumbling about the brooder), but got better in a day after I changed feed and gave nutri drench.
I have her ready to transport home now, to give her an epsom salt bath and check her over a bit more, then give nutri drench. What could this be and what else should I do? Thanks!!!

Hmmm - I looked at her eyes and one pupil has an irregular shape, but no grey at all, just the normal orangey color of the iris and then the dark pupil. But that’s probably bad news.

Can you post some pics of her and her eye? That may help others to better understand her condition.

 

[Stephine]

I will take some pictures.

I wouldnt fool with her and any kind of bath....see if she will eat some groceries from you and if she's hungry to get her strength up. Nutridrench is good...
Keep her immune system up, dont do anything to cause any undue stress.

An epsom salt bath can really revive a droopy chicken, so it’s not fooling around with her, but I am mostly worried about Mareks now, where yes, that treatment would be useless. I will give her nutri drench and if that does nothing, assume Mareks...

Ok, here are some pictures - first of her normal eye, then the a few with the odd shaped pupil. She is in the shade now with her pupils dilated more than earlier which makes the irregular shaped pupil less obvious, but you can still see it’s not round.

Hmm.
Are you sure she was vaccinated?

 

[Stephine]

Yes, absolutely sure - from Meyer’s hatchery. But, of course the vaccine is „leaky“, so she can still get ill...

@microchick @Folly's place

Calling in a members living with Mareks. Folly's Place do I recollect correctly?
Three year old hen. Can a hen have ocular and neuro Mareks at the same time? OP thinks hen was vaccinated.
I know it really depends on the strain and the vaccine used. Theres also such a thing as vaccine failure.
Thoughts?
