We have 25 laying hens and 25 pulits. Two weeks ago we noticed some hens having swellon eyes, wheezing, sneezing, nasal discharge, eyes glued shut on some, and open-mouth breathing . We didn't noticed any odor. Also, they have completely shut off laying. Someone said the hens could be multing and we beleive they are. We gave sulmit (spelt wrong) and it seems to clear everyone up. We washed all feeders and waters except our large feed; its make of wood. We clean out our coop often, my husband is a neat freak about his coop. We have also noticed some diarrhea, and they don't seem to want to drink. We have poo in multiple colors from green to tan, white and orange combination. Can any one helps us figure out whats wrong and why our birds seem to be sick AGAIN? My husband is just sick about his herd and afraid it could be something really bad.
