I got the results back today on my little hen I sent to ISU-on exam and hx looked like Mareks, on gross necropsy inflammed nerves, muscle loss and no fat around heart or gizzard, histopath results are not consistent with mareks though may have had a spinal injury but no definite dx. So glad it wasn't mareks. hated to sacrifice the girl, but for the well being of the flock had to. Cost is minimal I think should be around 25 bucks.
