3 Year old Dorking can't see and sleeping a lot

[chookfamily]

For the past 5 days our hen has been sleeping a lot and bumping into things and walking off edges. We've been hand feeding her but she pecks randomly to the left and right of our hand, when she walks she lifts her feet up really high and seems to have no idea where she is. Any ideas?

It could be any number of things...
Including marek’s disease.
Have you recently introduced any new birds to your flock from “the outside”?

Here is some information you may want to read over
