Hi ya'll-- We have ten young turkeys, living pretty closely with chickens (I know, I know... it's risky, but we haven't had problems before!) and one of the turkeys is leaving behind wet droppings that are KIND OF yellowish--not the sulfur color that I've heard described for blackhead, just a yellowy kind of light brown. I've been finding the droppings for about three days now, so its more than a one-time deal. None of the turks look sick or lethargic, and we don't know which one is leaving the droppings, as they're all free-range. I'm getting pretty nervous that it might be blackhead, but I don't know which bird to quarantine or treat! What do you think? Should I be concerned? Treat the whole flock? Follow them around all day as a poop-sleuth to figure out which one is leaving the mystery droppings? Ack! Help!
