Hi guys! My chickens have come down with an illness. It started off with my Leghorn hen. It was 110F before the heat index and she was panting, sounded kind of gurgley. I didn't think too much of it because it's hot, even with a mister and a breeze.
She started sneezing last week and doing this sharp inhale where she's almost clucking backwards, if that makes sense. I've noticed my other birds are starting to sneeze.
I thought it was from the heat and us mowing after a few rain showers but it's gotta be something in their system.
They've all had a healthy appetite and when allowed to forage instead of being confined in their electric poultry net, they have a lot of energy. They're just sneezing and my Leghorn sounds awful. No wrinkled eggs, smellyness (other than the usual stinky poop), and no watery eyes, not even from the Leghorn.
I want to treat everyone so I can make sure they're all okay. What should I use and what should be the egg withdrawal time?
Thanks y'all!
