I got a new hen today, and she was fine. Then when we got her into the heated truck she started to sound clogged up. She is still sounding a bit stuffy... nothing really draining, but almost like she is wheezing a bit or something. Its almost like when you go in and out of the heat and you get a runny nose. The gentleman I bought the hen from had a healthy flock. She did not start this sound until we got in the truck... any ideas? Apple cider vinegar? Tylan? Anti Biotics?
