The last few days my 3, 3 week old chicks have been intermittently making an odd noise from their nostrils. It sounds like a sneeze. occasionally some liquid will come out but mostly not, all are totally well otherwise. Eating, drinking, running around as chicks do. I ordered some Vet rx and applied it under thir wings. Has anyone dealt with this and their chicks been fine? the internet is a gloomy place when looking for answers. Tried to include a small video of a "sneeze " in action
