HI all, one of the girls is sounding like she is purring this mornig and I know that this not a normal sound for her. Eating scratch but it sounds very odd. I tried massaging her crop and can't feel anything but it's very odd. Any suggestions very welcome, it's distressing to hear her breathe like that. I suspect she got into bird seed and ate a sunflower seed-the little birds strew their seed everywhere.
