I just bought a few new chicks to add to my flock over the weekend. (1) Mauve Silkie, (2) Chocolate Showgirl Silkies, (2) Lavender Orps, and (2) Zombie Bantams. The Chocolate Silkies keep sneezing. No other symptoms. I did see one red stool, not sure who is was from, but I have not seen any since. The silkies are the oldest they hatched the 4th while the others hatched on the 10th. I'm giving them all medicated feed (with amprolium) and I am going to add nutridrench later today. Any other things I could be missing? Or anything else I need to do? At this point, since they've all been together over 24-36 hours, I figure I need to make sure they're all treated. Any help is greatly appreciated!
