1) What type of bird , age and weight. Barred Rock/Cuckoo Marans, 18 weeks old, not sure on weight. She looks good size and feels solid for a gal her age. 2) What is the behavior, exactly. I came home from work today and she was making a wheezing sound while breathing. She also sneezes. 3) How long has the bird been exhibiting symptoms? I noticed she sneezed a few times yesterday 7/10/11 4) Are other birds exhibiting the same symptoms? The other 9 are fine. 5) Is there any bleeding, injury, broken bones or other sign of trauma. None 6) What happened, if anything that you know of, that may have caused the situation. We have been using the mister on a daily basis in the run (on a timer) and they have a/c in their coop 7) What has the bird been eating and drinking, if at all. She still eats and drinks very well. 8) How does the poop look? Normal? Bloody? Runny? etc. Poop looks normal. More wet then the formed. 9) What has been the treatment you have administered so far? I just put some Duramycin in their water. 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? I would like to treat on my own but I do have a vet that will see my girls if need be. 11) If you have a picture of the wound or condition, please post it. It may help. ) Describe the housing/bedding in use. They have sand in their run and coop. Housing is cleaned every day. Coop is insulated with a ceiling fan as well as a/c set at 80. I picked up Phoebe and looked into her mouth and throat to see if maybe something was stuck. She ate watermelon, corn on the cob, BOSS and her crumble yesterday. She also had cottage cheese with oatmeal and peas in the morning. Nothing out of the ordinary she has eaten. I am just curious if maybe she got too wet from the misters to cause maybe a respiratory infection. ( the girls usually get misty and then go lay in their shady place) There is no signs of bubbles coming out of her nose. I decided to put the Duramycin in the water as I had one gal have bubbles come out of her nose and sneezing 9 months ago. Also can you eat their eggs while they are on the Duramycin treatment? Any help will be appreciated. this is her now!!!! I am really afraid she will pass away tonight. ***UPDATE*** Just got back from the emergency vet. Phoebe is in critical condition and was put in an oxygen box. Her throat is swollen and she will be getting an anti-inflammatory injection. She also will be receiving fluids. Dr think it's respiratory. Praying she makes it through the night till tomorrow when we see our regular vet. She is spending the night at the ER Vet. My poor girl. I am a wreck!!!!
