Hi, My chicken is wheezing, coughing and sneezing. He wheezes after he crows and sneezes a lot. he has recently just survived a near death experience with heat stoke (that unfortunately killed all of our other chickens) i was wondering if his wheezing and sneezing had anything to do with this? He is normally very healthy and likes to peck, but when we checked him this morning he hasn't made a sound and didn't want to wake up. i have read that bread dipped in olive oil helps but so far he hasn't eaten any of it, i have also read that scrambled egg helps? this has been happening for about a week. Thank-you!
