So my chickens are about five months old, and one is beginning to lay. (Yay!!) But one of them, she's half Polish and half Americana has recently been making this odd squeaking noise. She looks like she's sneezing when she doesn't but it doesn't sound like a sneeze. She literally sounds like a dog's squeak toy! I checked for runny eyes or nose and she's fine. She's acting totally healthy as well. I did some research but I've gotten a lot of mixed results, does anyone know what this could be?
