I have to agree. I've had bulging eyes, but not hydrocephalus. And if casportpony hasn't seen it yet I am not sure you will find anyone who has. I am sorry I am not of much help. Did you hatch this keet from your own eggs?
I have a day old keet with a bulging eye. It looks as if there is no eye socket and the eye grew on the outside of the skull, rather than being recessed into it. How did your keet fare? Mine is a bit slow and sleepy. In fact he sleeps standing up half the time. He is eating and drinking but come to think of it I dont recall seeing any poop. Im following the advice in another thread. I do believe it is a deformity rather than infection but due to his sluggishness just don't know. I hate separating him but if it is infectious I do not want to expose other keets.
I have a peachick that looks like that.
