What a really busy, helpful site. Thanks all for the help. My hen is looking much rosier. Her comb is getting brighter pinkish red every day & starting to stand up & she is walking around on her own good. Much more energy & her voice is stronger. Still light as a feather. I think I will keep her separate until she's good & strong, then watch her to make sure the others let her eat. This is her 5th day of Sulmet/Tetra. She's getting poly-vi-sol, 30% cat food soaked, laying pellets & scratch. Always hungry. She looks to be on the road to recovery, I can't believe it, I thought she was a gonner. When would be a good time to worm her & with Wazine & then Safeguard? Thanks again.
