i think our hen may be wheezing, but im not sure. i woke up this morning and heard her making a strange sound.... it sounds flatter than her usual buck buck and more drawn out. as the day went by it stopped. now shes clucking but her voice may also be a bit more crackly than before. she still acts normally and eats/drinks, but her voice seems off. yesterday she just sang her first egg song, so we are expecting eggs soon. i did some research and saw that it may be a respiratory issue or gapeworms, to which either tylan or fenbendazole would work....? she has no other symptoms, just her voice is off. my mom is convinced that the change in sound is because shes supposed to lay soon.... but that sounds iffy to me. we have been doing construction in our backyard building the coop for the past couple weeks, maybe it got a bit too dusty for her?
