Went to my first chicken swap. I bought several additions and am happy BUT. I bought 3 larger black hens and they started acting odd in the car. Almost sounds like they have hiccups and they are panting. They have water now and food. My daughter insists she heard coughing. I sat back there for an hour and never heard a thing. The only thing I notice is after they drink they make the hiccup sound and shake their head funny. I have ACV out and I just put some water with a bit of antibiotic in it. Their poop looks ok. They had a couple poops when they first got in the cage that were runny yellow but after they were in the cool of the car and settled they pooped a ton and it was all pretty normal looking. I would say 2 out of probably the few dozen poops looked odd. So is this just it was hot, they are under stress and needed water or should I be segregating just a bit further away and crossing my fingers?
