I'm in fear my girl has Newcastle disease.... when the chickens have "paralyzed" wings or legs are they completely paralyzed? or do they just go limp? how long does it take this disease to kill? My girl had shown similar signs to the twitching I have seen in videos but it is DEFINITELY NOT the seizure like severity. It's more like her body jerks sometimes when she is laying down. What do you guys know about this disease so I can help narrow it down... I certainly will not allow it to infect my other girls as I would literally have nothing to live for if they died
