My black sex link hen was scratching with her feet at her face and then shaking her head, and when she shook her head this gooey thing flung out from either her mouth or nose I didn't see, and flung on the side of the chicken wire . I took it inside and took some pics, Can anyone tell me what this is from??? Hope its nothing too serious!! Thanks ( Sorry for how big the pics are! ) any suggestions/opinions on what this thing is/what it is from will help.
