My six year old barred rock hen has become lethargic over the past two weeks. Her poop is runny and yellowish and eats and drinks very little. I took her to the vet who x-rayed her and probed her for internal laying. He did not find any trace of an egg but her lungs were not clear, i.e. they showed a reduced volume of air. She had labored breathing but was not panting and no mucus was evident. Her temperature was normal (103.5). He prescribed an anti-biotic. After a week, there was not noticible improvement so we switched anti-biotics with no improvement still. I received advice that she might have parasites (lung worms) so I treated her with Ivomectin. She seemed to intially improve but now she is back to being lethargic, not eating, drinking very and her poo is still yellow with increasing amount of white in it. She now has brown liquid coming our of her beak when I open it and her nostrils are moist, but not runny. I am using a product called "Vet Rx" from the feed store that is an old remedy with camphor in it to specifically treat poultry with colds. I am stumped as to what else to do. I'm thinking she has a cold but perhaps she has parasites that died in her respiratory system that are giving her problems. Does anyone have a guess or suggestion as to what I could do? 1) What type of bird , age and weight. [barred rock, 6yrs old, 4.5lbs 2) What is the behavior, exactly.[lethargic, occasionally drools dark brown liquid, yellow/white droppings, no appetite) 3) How long has the bird been exhibiting symptoms? two weeks 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. None that I'm aware of 7) What has the bird been eating and drinking, if at all. Very little water, almost no food. 8) How does the poop look? Normal? Bloody? Runny? etc. Runny, yellow/white but low in volume 9) What has been the treatment you have administered so far? See above 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 for her to recover, my vet is out of ideas 11) If you have a picture of the wound or condition, please post it. It may help. 12) Describe the housing/bedding in use. She is in a 30x30ft fenced dirt floor chicken yard in the day and roosts by herself in a nesting box in the coop shared with 8 other hens at night.
