I have a blue Swedish, mallard and a black runner hens. They are a year old. I also have a mallard drake. They are a family unit. They stay in a coop except for evening.
There has been a runny nose issue going around on my flock. One hen is having a hard time breathing still. I think she may have started it but she still lays. Another hen had it for a week and recovered. I have a another one who is lethargic, running nose and not eating much. Any suggestions.
