Please someone help me. I just posted about a chicken that is falling over and is so weak she is sitting on her hocks? She's skin and bones but has been eating and drinking in the house. I originally posted that just she was affected but I just went out to clean the coop to find my favorite silkie is now presenting with the same ataxia and incoordination. They both look like they are drunk and can't stand without falling over. The silkie is doing the exact same thing today with just standing with the flock but is lethargic. I seriously need some help. What causes this stumbling? What can I give them. What if the whole flock ends like this? Somebody has had to experience this before. Anyone????????
