Noticed our two cockerels making weird noises, but I figured they were just finding their voice. Now that our Maran hen is wheezing when she breathes, I realize the cockerels are sneezing and shaking their heads. Their eyes are Not watery or swollen, and their noses show no signs of mucus. We have a flock of 22. How do I treat this before it gets worse?! Will something like apple cider vinegar or coconut oil in their water help until I can get some meds from the feed store? And what would you recommend? First flock, so never dealt with sick chickens before.
