Half Blind Leghorn! MAREKS! I STILL NEED HELP!!!!

Discussion in 'Emergencies / Diseases / Injuries and Cures' started by matthewschickens, Jan 20, 2010.

  1. We have a leghorn named Linda and it looks as though she has one blind eye.
    She is acting fine and she layed today. Does this happen alot in Leghorns?
    Is there anything I can do about it?

    This is her good eye:

    This is her bad eye:

    This is both of her eyes. The one on the left is her bad one and the one on her right is her good one.

    Any help will be very much appreciated!!

    does her pupal dilate at all on the bad side? I am wondering if its birth defect and maybe she just has reduced vision in that eye

    I don't have much experience dealing with this sort of thing, either. In my poultry book, it says to test for blindness slowly move your finger towards the bird's eye. If they blink, they are not blind. You have to do it slowly and straight at the eye... if you disturb the air, even a blind bird will blink. To test for pupil reactivity, just grab a flashlight. A normal pupil will get larger when it is in shadow and get smaller when a light is shined in it.

    I don't think there is a cure or even a treatment for Marek's disease. (If that's what this is!) Many people will cull affected birds at the first sign because it is highly contagious. There is a vaccine available, but I don't know anything about administering it. It may be worth it to get some professional advice. When one of my birds was sick I contacted the "chicken doctor" Peter Brown at First State Veterinary Supply. He is not a vet, but has degrees in poultry science and tons of experience. A consultation is $25, but if you need any medication he will apply the $25 towards that. I was very impressed with his service. http://www.firststatevetsupply.com/ None of the vets around me will treat chickens, so this worked out well.

    I would suggest searching the forum and internet for marek's disease and reading all you can about it. Also, if you could tell us more about Linda and the rest of your flock it might help some of the more experienced members help you. For example, has her eye always been weird? If not, when did you notice the change? Does she "miss" when she pecks at stuff? Is she still eating, drinking, laying and pooping normally? How many birds do you have, are any others sick in any way, have any died recently? Have you separated Linda from the rest of the flock? (A good idea when illness is suspected!) Just a few things off the top of my head!
  6. Thank you for the advice!

    I do not know how long her eye has been weird.
    I first noticed it a few weeks ago
    As far as I know she is eating and drinking and laying eggs.
    I have 28 hens and a roo with her.
    None have had any signs on any thing but some are missing some feathers.

    have not seperated her yet but I hope to do it soon.
    I checked and she is blind in that eye and she does not seem to have any problem pecking.

  7. And one more thing:
    She had coccidiosis when she was younger.
    Does that help?
  8. Marek's typically will show up with symptoms of paralyzed legs, lost weight and a "puffed up" posture.

    Gray iris is an indication of Marek's, but not necessarily a prognosis or a diagnosis.

    I would, however isolate your chook in a cozy, warm cage.

    Personally, I think this is an injury or a birth defect. Watch the other eye carefully, usually they are NOT blind from Marek's and a gray iris signals a long term infection.

    One would know Marek's if one saw it. It really is pretty obvious.
  9. Thanks!

    Anyone else?
  10. Anyone?
