I have a 3 month old pullet that got sick yesterday. I found her having difficulty walking but she was unsteady equally on both legs, not just one as is often described in common symptoms of marek's. Initially I thought she was having a heat stroke because temp was near 100. I ran some cool water over her legs and under her wings. She didn't improve and in fact soon was worse. She got weaker and wasn't trying to walk at all. She was doing nothing but laying down with neck twisted and I noticed a foul smell at her rear. She is still alive a day later but has done nothing but just lay in her box and drain a very foul smelling brownish green diarrhea. I don't see any blood in the drainage. She is aware of what's going on around her but she isn't moving at all. I know it's time to do something and I am planning on having a necropsy done as I have a lot more chickens with most of them 3 months or less in age so I need to know what this is. I have read symptoms of Marek's and diarrhea is mentioned but I have not seen any mention of a foul smelling diarrhea. Anyone else had similar experience? thanks!
