Hen Unable to Walk

[OnionRanch]

Hello! This is not my chicken, this is my aunt’s. This hen is of laying age. She as of today became unable to walk. No sign of bumblefoot on her feet to my knowledge. Another chicken died two months ago, she didn’t want to move or walk either. My first thought is Mareks... what do you guys think? Maybe not?


Update! No mites near her vent, and she is drinking slightly when held up next to water. She cannot walk at all.

Is she a young hen? How large is the flock? Have you tried adding any vitamins?

My aunt said she has been giving the hen sav-a-chick electrolytes alongside regular water. The flock is about 6 chickens, and has more than adequate space, a large well ventilated, clean and safe coop. The hen is just over a year old. No improvement today, I suggested Euthanasia and a necropsy. Does anyone know what is wrong with her though?
