I have a kinder milking doe that I noticed today while milking her, she was having an unusual hard time eating her grain. I looked in her mouth, it looked normal, no sores, pink like it should be. Then, I gave out treats before I left for work, she usually wolfs it down, took a few chomps and then spit it out? Any ideas?? She was grazing fine, she's acting fine. I thought it was kind odd, I've never seen her do this, or any if my others for that matter.
