In my experience the "..." in a bubble precedes the skull in a conversation bubble which indicates that the animal is sick and needs to be treated.
If that is not happening and the animal is not upset, I would cut the grass into fodder with your sickle and keep an eye on the animal. There may be something happening but it may not be what you think.
I had a chicken I worried wasn't eating but it never appeared sick. I had to just stop worrying and when I left everyone inside, because of the weather, whoever wasn't eating started eating. I never figured out why I had a chicken not eating but it stopped.
You should get at heart in the bubble over the calf's head when you talk to her the first time everyday. As long as that is happening don't worry.
