We have a lot of chickens and when it gets cold there nose will get a lil runny, and it’s clear and they sneeze . But this isn’t like sick type sneezing if you get what I mean. I’ve dealt with mycoplasma before I don’t let chickens stay in my flock that have had it. This isn’t mycoplasma and I don’t think there sick I’m just curious if that stuff happens to perfectly healthy birds?
