Yesterday I came home to find one of my standard sized EE's (purchased as a chick from feed store, who gets them from Welp's in Iowa) slumped in a corner under the porch. She was already laying earlier this summer, but quit a month or so ago, and never started again. One leg was obviously paralyzed, and when she was moved around, she coughed a lot and hacked out some spittle. I placed her in a dog crate, and she flopped over on her side. She would not drink, and kept her head hunched down and eyes closed. Her eyes did look a little funny, like sunken back in the head, one more than the other. This morning she was dead. I am unfortunately worried that I have Marek's in my flock, but I haven't quite determined this for sure. The symptoms also sound like Newcastle's possibly. I have not opened up this bird yet to see if she has any tumors. She did not have diarrhea, and never pooped at all the whole night, and there was no poop under her when I found her. A few days ago I noticed she did not come off the roost to eat, but when I took her down, she acted normal. Does anyone know if Welp's vaccinates for Marek's? I had a young banty roo that I culled a couple months ago b/c it had the jiggles and shakes and fell over all the time, and a younger one exactly the same feathering color was starting to do the same. Both were culled. Several of my birds sneeze occasionally, this squeaky noise, which they tend to do when they are eating or drinking. Anyone have any ideas? I have all different ages and types of chickens, mixed, EE's, a polish, japanese bantams, etc. Old ladies all the way down to a fuzzy youngun'.
