I had 10 RIR hends in the last two days I have lost two, one of the hens had a clear mucas around her nostrils. When i instpected the other ladies tonight it seems when i pick acouple up you could hear whezzing in there lungs, I saw no bloody stool everything looked solid I had just changed there bedding prior with new hay I'm getting ready to change it again and want to clean there coop out. I its a wood floor I figure that hot water and lysol should work for it hopefully. Just wondering what kind of medication i can give them to help fight off what ever they have. There not a year old got them all at the same time. the weather has changed also which has brought there egg production down, recently I fenced them in because when the dogs open the doors in the house to go outside the chicken would come inside and my wife didn't care for that all. well its 3:23 am here in california think ill try to get some sleep check the forums in the morning and call the vet and the local feed store also. btw all my chickens are named Isabel's, so an advice to help my isabel would be very greatful.
