I have 12 chicks i got about days ago to add to my flock. The first day i noticed some sneezing but no biggie. Then i noticed one of my speckled sussex was wheezing and sneezing a lot. Ive added nutri drench to the water because thats all i have at the moment. Sh doesn't seem to be wheezing today. I did notice this am that one of the gold sex links was doing this yawning thing and sneezing from time to time. Everyone is acting totally normal. Eating, drinking, pooping, chirping and running around. What should i do at this point I've never experienced this?
