Have made a terrible mistake purchasing hens from a well known country store from an independent poultry breeder and two are sneezing. Had to dispatch my silkie cockerel last night as really poorly, couldn’t breathe, snotty nose and watery eyes. He seemed so distressed, today his companion silkie is sneezing and again is very rattly. Have now separated all three but worried now it’s infectious. Have never had anything like this in my 10 years of hen keeping. I’m suspecting I need antibiotics but I know the vet will want me to take all 3. Have given all some respite in drinking water for last few days, any other recommendations, many thanks
