here is my situation that i think may have contributed to all of this! this past thursday i got home from work to find my garage door open where my chicken coop is kept for the winter. not sure how it could have been opened since i was sure i closed it when i left for work that morning. nothing is/was missing from the garage so i don't think someone had entered to steal anything, believe it may have been popped open from the wind. we had a big storm hit our area the day before so lots of snow and cold in our area, been down to the single digits and teens lately. it still gets cold in the garage since i have not been trying to heat it but it still stays about 5-10 degrees warmer than outside temps. 1) What type of bird , age and weight. mostly bantams-favs, cochins, and lost my brahma last night and one of my young favs this morning and another fav on her way out! 2) What is the behavior, exactly. acting lethargic and not eating, staying away from others in flock, goopy eyes turning into stuck closed eyes, gasping for breath with a stench and appears swollen in the mouth with bumps! and then death 3) How long has the bird been exhibiting symptoms? 2-3 days and then death 4) Are other birds exhibiting the same symptoms? about half of flock 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. sudden temp changes and draft due to door getting pulled open 7) What has the bird been eating and drinking, if at all. cracked corn, game bird crumbles, and just gave some plain yogurt and lettuce today to get them all eating. those not showing the symptoms seem to be eating fine while. 8) How does the poop look? Normal? Bloody? Runny? etc. i have seen some blood spots in poop with slightly runny but green poop. birds separated don't seem to have much poop and it is runny with just the white part. 9) What has been the treatment you have administered so far? tylan mixed into water and mixed into yogurt. 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 need to treat myself since we have no chicken vet around and local vets don't treat birds or understand how to. i am planning on taking a corpse to our local University since they do the necropsy there and my birds are NPIP. 11) If you have a picture of the wound or condition, please post it. It may help. 12) Describe the housing/bedding in use. just did a partial change in pine shavings a week ago. please help me! i am stuck here on this one! also, there is sneezing and nasal discharge on most of them. if the goop isn't already coming out of they eyes.
