I introduced five new pullets to my flock of 4-year old beautiful, healthy aracanas and within one week two of my aracanas came down with a respiratory illness. Everyone has been very helpful with advice. Their symptoms at the time included clear runny eyes, eyes were closed sometimes and a weazy, gurggling breathing. I noticed that a third aracana started sneezing so I opted to treat the entire flock. I treated the two ill hens with VetRX and Agrimycin powder (oxytetracyline HCI) in the water. I started treating the hens last Friday, it has been 4 days and they are so much better. The eyes have cleared up, they are foraging on the lawn and the wheezing has stopped. How long should I keep everyone on antibiotics, the package says 7 days. I have been disgarding the eggs and had decided to disgard all eggs for a week after the hens are off of the antibiotics, is this correct? I do not sell the eggs, they are just for family and friends. The girls are on pine shavings on top of dirt, the coop is clean and airy. They have a large outside enclosure and they are free to roam anywhere on our farm from about 3:00 pm until about 7:00 pm when they put themselves up. They are, by the way, under the watchful eye of a labrador and a Jack Russell who both "protect" their flock from foxes and the neighbors dogs!
