My husband had let the chickens out of their coop when he left for work early this morning and said everything was fine. I woke up a couple hours later to a strange constant crying sound. I checked on the chickens and one of them is 'crying'. She is about 1.5yrs. old and finished molting a couple weeks ago. If you go to youtube and search 'chicken crying?', it is a video of what my chicken is doing. (This is not my video), but that chicken is doing exactly what my chicken is doing. There are no responses, so I don't know what is causing this. I'm concerned that the crying will attract predators, but I do have goats, so hopefully that would deter anything from coming in the yard. She comes for corn treats, but does not eat. She does chase & eat stinkbugs flying around, but usually just stands and constantly cries. Even when walking around she cries, like the video. Has anybody experienced this before? Do they stop the crying? What could it be? I've googled it and come up with, upper respiratory illness, could be a tick on her, or any number of reasons. Any help would be appreciated. Thanks.
