I have silkies. I had a 7 month old girl start looking kinda puffy then found her in the run kinda seizing this happened two diff times weeks apart then dead in coop. She did feel very thin. ( I wormed everyone after I noticed her puffy & thin) then I have another silkie present w/ wry neck I treated her & she looked fine. Yesterday my one year old hen looks puffy bring her in give her heat & broad spectrum antibiotic & vitamins . She wasn't eating but drinking nonstop. Around noon I picked her up to examine her more she started seizing arching back head turned back & wings out. I haven't been able to get her up to sitting position just stays in that position & has tremors . This girl doesn't feel emaciated . Go in to my run tonight my previous girl w/ wry neck is falling over has yellow green diarrhea & puffy. Please tell me what I can do if anything .
