i have a call into my vet's office, but wondered if anyone has any ideas. Year and a half old silkie hen, staggering upon coming out of coop this morning, trying to hold self up with wings, very weak, breathing heavy. She had a bout of this staggering thing several months back. i brought her in the house and she was fine the next day. But she wasn't weak and breathing hard then. All my chickens were wormed, treated for lice, and coccidiosis and vaccinated for fowl pox in December. No bad reactions from anyone at the time. Okay, new development She just fell over on her side, legs straight out. Its like her body is paralyzed, and she just threw up some stinky brown liquid. Ack! i need my vet to call me back!
