One coop of my daughters bantams are showing respiratory problems. She has 4 large breeder pens in this coop. Several have begun sneezing, breathing with beaks open and you can hear raspy breathing, especially at night. All have been healthy, wormed late summer. For the past two months I have been fogging the coop and chickens once a week with oxine, I hoped as a preventative. There are 2 are newer arrivals, shown and purchased at a show in early October from different breeders. The new birds were in quatantined for over 3 weeks before being moved into this coop. Our other birds that were in quarantine with them (went to the same show) are dong fine, they live in a different coop. So far none have any noticable nasel drainage (bubbly crud), I cant see any thing unusual in beak, all are active and eating well. But there is snezzing and raspy breathing that you can hear if you listen real close during the day and noticable when on perches at night. One cockerel is breathing with beak open at night. What we have done: Started on 11-21 Treated water with Tylamox from Foys (20 mg Tylan & 10 mg Amoxicillan), changing water daily Using vetrx, warmed and puttiing a drop in each nostril of birds who are having breathing trouble Fogging coop and birds with oxine each morning Encouraging eating, scrambled eggs and fresh chicnks of pumpkin in the morning Is this antibiotic the best for respiratory problems, it is all we have on hand but we have a vet who will dipsnce to us. Please dont preach about introducing new birds or not to medicate and cull the whole flock. These are my 10 year old daughters birds, she has worked hard to aquire good stock. She is the one who noticed that she thought she heard sneezing and that we should keep a close eye, next day it was obvious. I am glad now that she has her birds in several seperate coops. I know respiratory problems are not good. She was just setting up her breeding pen groups and got her new incubator. Ideas please.
