My 18 month old Bluebell hen has been making a sort of cough/sneeze noise lately. We have separated her for the past week or two from the other 12 hens and are keeping her in a separate eglu with large run. She is eating well, drinking, pooing and still laying (I have throw her egg away every day though as a precaution). She has no discharge from her beak or eyes. She has been treated for worms with vermx for 3 days in her food, my son has checked her throat to see if anything visible, she has been given some olive oil to lubricate her throat, cider vinegar in her water, and extra foody treats including fresh herbs which should be beneficial. I happened to be at the vet to get one of my cats spayed last week and asked their advice and they said there wasn’t anything more I could do but monitor her as if they prescribed antibiotics we could never eat her eggs again. We would be fine with that as we have enough other hens but her egg isn’t distinguishable enough for us to know which is hers. I’m at a loss - obviously I don’t want to let her back in with the flock if it’s something contagious (and neither would I want to be eating her egg if it was an issue) but she is used to free ranging all day and I’m feeling her frustration of being literally cooped up all day. Any advice greatly received!
