I recently bought 20 chicks from a seller who all ended up being sick. It started as soon as i got them home. The older chicks I bought started sneezing weezing and gasping for air, they also had runny, crusty noses and they rank! Almost all the older ones have died, but 2. I had babies that were in the incubator when i showed up and i brought them home in a seperate cage, they seemed fine at first but then they started dying too, they have no symptoms though, they just get really lethargic and die. Im loosing this flock by atleast 3 a day. I have had them on duramyicin and vet rx since i first noticed symptoms, but its not helping at all. I called the state vet and department of Ag who agreed to do a free necropsy on 4 of them, but i have to wait 1 week for results, by then they will all be dead anyway! Im feeling hopeless here and that just may be the case but has anyone seen this before? Can anyone tell me what it is and if theres anything i can do? Because at this point im just watching these babies die Heres a pic of one of them thats pretty bad off, notice the red eyes, yellow crusty nose and that shes gasping for air.
