Yesterday I noticed one of my Buff Orphingtons looking a mess on the front like she threw up, & her comb flopped over. She was lethargic standing around acting weak & closing her eyes. She kept opening her mouth like she was trying to cough up something, but nothing coming up. Looked down her throat didn't see anything, her crop seems normal. Not eating or drinking anything on her own. Gave her water & a little milk through a dropper to keep her hydrated & nourished. She pooped once yesterday since I separated her & last night both were dark green & runny. h. Looking at poop phot os think it might be Clostridium perfringens. Poop has a strange smell ...almost sweet. Assistance appreciated.
