1) What type of bird , age and weight. BO hatchery, 26 weeks, weight unknown 2) What is the behavior, exactly. Found in chicken pasture standing, not moving with eyes closed mouth open. After a few days in quarintine she is moving around fine but is blind. 3) How long has the bird been exhibiting symptoms? Did not move for 2 days. Walks around fine now other than bumping into everything. Started a week ago. 4) Are other birds exhibiting the same symptoms? No 5) Is there any bleeding, injury, broken bones or other sign of trauma. No 6) What happened, if anything that you know of, that may have caused the situation. It was very sudden she was running around in the pasture that morning with other pullets. Personal research points to optical form of mereks. 7) What has the bird been eating and drinking, if at all. Yes, she has figured out where the food and water is, force feed water and food for first few days. Blindly stabs at grass and clover. She wants to eat. 8) How does the poop look? Normal? Bloody? Runny? etc. Normal 9) What has been the treatment you have administered so far? Given Oil of Oregano (natural antibiotic, anti virus, anti fungal) For first few days. 10 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet? 11) If you have a picture of the wound or condition, please post it. It may help. See pics 12) Describe the housing/bedding in use. Was in chicken tractor (see my BYC page), now in dog cage quarintine wtih pine shavings. My BO was very healthy, no bugs, organic feed, feathers look great and then all of a sudden this hit. From what I have read it sounds like mereks optical type. I'm very bummed because it seems like my only course of action is to cull. She just started laying and she still trying to run to us when I call to her. Is this Mereks? Can her sight come back? Is there anything I can do? thanks.
