my one yr. old hen has pale comb, blackish around points, kind of scaley looking. Poo normal. no mites that i can see. appetite dropping off from before. picked her up last nite, no wheezing, but when i put her down she just stood there with her wings down a bit and her breathing was labored. she just stood there for about 2 minutes. no fluid from eyes or nose. she has lost weight-can feel her breast bone and her crop can't be felt at all. she's interested in treats and eats just a bit, then just slowly walks away. i feed purina layina, oyster shell and suppliment with fruits/veggies/yogurt. my vet passed away last month, so i'm high and dry here!
