Good Morning, I seem to be confusing myself. I have chickens that are sneezing, have diarrhea and sound kind of raspy when they make noise. It's hard to describe. But...they're acting normal, eating and drinking, seem happy otherwise. I'm going out to purchase tetracycline for them this morning. Am I making the right purchase? The diarrhea is what is tripping me up. I'm going to get some yogurt for them, as well. Any other suggestions? Thanks!
