I have a 7 month old pullet who appears to be perfectly healthy. Good body weight, color, plumage ect.... But I noticed today that when she breaths she is making a kinda raspy squeaky sound when she moves air in or out. No sneezing, runny nose, or any other symptoms. Also, when I picked her up and was feeling her neck & crop area, I noticed that if I apply a little pressure next to her crop the noise stopped. Does any one have a clue what could cause this? Could she have something stuck in her chest? ????
