I went out again later. This time Sunny came up close much quicker than she had earlier. She still didn't want to touch her nose to the plastic scoop, though. I didn't have a lot of time tonight to sit and coax her. I did manage to give her a good scratch on her neck, then set the grain (still in the scoop) on the barn floor. Hopefully eating out of it tonight will let her know that it's okay to eat out of it while it's in my hand in the morning.
